Choosing the right knife sharpening angle can make the difference between an edge that slices cleanly and one that quickly rolls, chips, or feels unnecessarily dull.

A thin edge generally cuts more easily.

A wider edge generally provides more support behind the cutting edge.

The challenge is finding the right balance for the knife.

A hunting knife, EDC knife, Bowie knife, bushcraft blade, and chef knife should not automatically be sharpened at the exact same angle.

The right angle depends on:

• Blade steel

• Heat treatment

• Blade thickness

• Edge geometry

• Grind

• Intended use

• Existing factory or maker bevel

This guide explains common sharpening angles, what degrees per side actually means, and how to choose an appropriate edge for hunting, outdoor, EDC, Bowie, and handmade fixed-blade knives.

Knife Sharpening Angle Chart

The following chart provides general starting ranges, not universal rules.

Knife Type	General Angle Per Side	Main Priority
Fine slicer	12–15°	Maximum slicing efficiency
Chef knife	15–20°	Sharpness and food prep
EDC knife	17–22°	Everyday utility
Hunting knife	18–25°	Cutting performance and durability
Skinning knife	17–22°	Controlled slicing
Bushcraft knife	20–25°	Outdoor durability
Bowie knife	20–25°	Strong general-purpose edge
Survival knife	22–25°+	Edge support and rugged use

The safest starting point for most existing knives is simple:

Match the angle already on the blade unless you have a specific reason to change it.

Reprofiling to a different angle removes more steel and changes the original edge geometry.

What Is a Knife Sharpening Angle?

The sharpening angle is the angle between the sharpening surface and one side of the cutting edge.

Most double-bevel knives have an edge sharpened on both sides.

For example:

20 degrees per side = approximately 40 degrees total included angle.

This distinction is important because people sometimes say “20-degree edge” without specifying whether they mean 20 degrees per side or 20 degrees total.

When discussing hunting and outdoor knives, sharpening angles are commonly described per side.

What Does “Degrees Per Side” Mean?

Degrees per side is often abbreviated as DPS.

So:

• 15 DPS means 15° on each side

• 20 DPS means 20° on each side

• 25 DPS means 25° on each side

A 20 DPS edge therefore forms an included angle of approximately 40°.

Lower DPS creates a thinner edge.

Higher DPS leaves more steel behind the edge.

That creates the basic tradeoff between cutting efficiency and edge durability.

Lower Sharpening Angle vs Higher Sharpening Angle

Understanding this tradeoff is the key to choosing an angle.

Lower Angle

A lower sharpening angle creates a thinner edge.

Potential advantages include:

• Easier slicing

• Lower cutting resistance

• Fine edge performance

• Good precision cutting

Potential disadvantages can include:

• Less steel supporting the edge

• Greater possibility of rolling or chipping depending on steel

• Less tolerance for rough cutting

Higher Angle

A higher sharpening angle creates a more supported edge.

Potential advantages include:

• Greater edge stability

• Better tolerance for demanding use

• More material behind the cutting edge

Potential disadvantages can include:

• More cutting resistance

• Less fine slicing performance

• Edge may feel less aggressive

Neither approach is automatically better.

The right angle should fit the knife.

What Angle Should You Sharpen a Hunting Knife?

For many hunting knives, somewhere around 18–25 degrees per side is a useful general range.

But that range is intentionally broad.

A dedicated skinning knife may benefit from a somewhat thinner slicing-oriented edge.

A more general-purpose hunting blade may use a wider edge for additional support.

A thick outdoor hunting knife and a thin caping knife should not automatically have identical edge geometry.

Consider what the knife is designed to do.

 

How to Sharpen Your Blade for a Sharper Edge

Knowing how to sharpen a knife properly is one of the most important parts of good knife maintenance. A well-maintained edge improves cutting performance, control, and helps you get more life out of your blade.

Before you sharpen your blade, pay attention to the blade angle. Keeping a consistent angle while sharpening is more important than applying heavy pressure. Different knives may use slightly different sharpening angles, so try to follow the existing edge whenever possible.

For experienced users, freehand sharpening with a whetstone offers excellent control and allows you to follow the natural shape of the blade. Use smooth, consistent strokes on both sides of the edge and check your progress frequently.

The goal is not to remove as much metal as possible. Instead, focus on maintaining the correct blade angle and gradually creating a clean, sharper edge.

Regular sharpening, cleaning, drying, and light oiling should all be part of your normal knife maintenance routine. Taking care of the edge before it becomes extremely dull makes sharpening easier and helps keep your knife performing at its best.

How to Sharpen Your Blade and Create a New Edge

Learning how to sharpen a knife correctly is an essential part of proper knife maintenance. A well-sharpened blade cuts more efficiently, feels safer to control, and helps prevent a dull knife from becoming harder to restore later.

Before you begin, identify the existing blade angle and try to maintain the correct angle throughout the sharpening process. Consistency matters more than pressure. If you struggle to hold the angle by hand, an angle guide can help you maintain a steady position while working.

For traditional freehand sharpening, sharpening stones are one of the most effective tools. Start with an appropriate grit depending on how dull or damaged the edge is. Use smooth, controlled strokes and avoid using excessive pressure.

The goal is to remove metal gradually and evenly until both sides meet to form a new edge. As you sharpen, you may begin to feel a burr forming along the opposite side of the blade. This is a thin ridge of metal that indicates you have sharpened far enough on that side.

Once a burr has formed consistently, switch sides and repeat the process. Proper burr removal is important for finishing the edge cleanly. After sharpening, lighter strokes on a finer stone can help refine the edge and reduce the remaining burr.

For an even cleaner finish, use a leather strop after sharpening. Stropping helps remove microscopic burrs and polish the cutting edge, giving the knife a smoother and sharper edge.

Regular sharpening should be part of your overall knife maintenance routine. Rather than waiting until you have an extremely dull knife, touch up the edge periodically. This makes it easier to maintain the correct blade angle, reduces the amount of metal you need to remove, and helps your knife perform consistently over time.

Hunting Knife Sharpening Angle

A practical hunting edge needs balance.

You generally want:

• Clean slicing

• Controlled cutting

• Reasonable edge retention

• Enough stability for field use

• Sharpening that can be maintained without unnecessary steel removal

For many general hunting knives, around 20–22 degrees per side can be a reasonable reference point.

However, preserving the knife's existing bevel is usually better than choosing a number just because a chart says so.

Skinning Knife Sharpening Angle

A skinning knife places more emphasis on slicing.

That means some skinners can benefit from a slightly thinner edge than a rugged survival blade.

A general range around 17–22 degrees per side can make sense depending on:

• Steel

• Hardness

• Blade thickness

• Grind

• Intended cutting

A thinner hollow-ground skinner may behave very differently from a thick flat-ground hunting knife even if both use the same steel.

The blade design matters.

What Angle Should You Sharpen an EDC Knife?

EDC knives usually perform everyday tasks such as:

• Cardboard

• Tape

• Packaging

• Cord

• Light utility cutting

For many EDC knives, 17–22 degrees per side provides a useful balance.

A thinner EDC blade used mainly for slicing may work well toward the lower end.

A thicker outdoor-oriented EDC fixed blade may benefit from a more supported edge.

The best EDC angle depends on the steel and how the knife is actually used.

What Angle Should You Sharpen a Bowie Knife?

A Bowie knife normally has a larger and more substantial blade than a typical EDC knife.

Many Bowie knives also have thicker blade stock.

For a general-purpose Bowie, approximately 20–25 degrees per side can be a useful reference range.

That does not mean every Bowie should automatically be sharpened to 25°.

A collector Bowie with a relatively thin grind may use different geometry from a rugged outdoor Bowie.

Steel and heat treatment also matter.

For example, 1095 carbon steel and D2 may respond differently depending on hardness and blade construction.

For more on those steels, read our 1095 vs D2 vs Damascus Steel guide.

Bowie Knife Angle: Why Blade Thickness Matters

Large Bowie knives can vary dramatically in blade thickness.

A thick blade already has more material behind the edge.

If the edge bevel is also extremely wide, cutting resistance can increase substantially.

That is why sharpening angle cannot be separated from blade geometry.

Consider:

Blade thickness + grind + sharpening angle = overall cutting geometry.

A thinner flat-ground Bowie at 20 DPS may behave very differently from a thick saber-ground Bowie at the same angle.

Bushcraft Knife Sharpening Angle

Bushcraft knives are often designed for:

• Carving

• Feather sticks

• Woodcraft

• General camp work

Many bushcraft knives use Scandi grinds, which can change how sharpening is approached.

Instead of maintaining a tiny secondary bevel, many traditional Scandi knives use the large primary bevel as the sharpening reference.

Other bushcraft knives may use conventional secondary edges.

For a normal secondary bevel, 20–25 degrees per side can be a useful general range for durable outdoor geometry.

But if the knife uses a true Scandi grind, follow that grind rather than automatically adding a new secondary edge.

Survival Knife Sharpening Angle

Survival-style knives tend to emphasize rugged outdoor utility.

For these blades, a wider edge may make sense.

A general reference range of 22–25 degrees per side or more may be appropriate depending on:

• Steel

• Blade thickness

• Intended use

• Grind

• Edge thickness

Again, this is not a requirement.

A good survival knife should be sharpened according to its actual design rather than an internet number alone.

Does Knife Steel Change the Best Sharpening Angle?

Yes.

Steel affects how thin an edge can reasonably be while maintaining stability.

Important steel characteristics include:

• Hardness

• Toughness

• Wear resistance

• Carbide structure

• Heat treatment

A very tough steel may tolerate geometry that another steel does not.

A highly wear-resistant steel may hold an edge longer but require more effort to sharpen.

This is why sharpening-angle advice must be paired with steel knowledge.

Sharpening 1095 Carbon Steel

1095 is popular on outdoor fixed blades because it can offer a useful combination of toughness and straightforward sharpening.

Depending on heat treatment and blade geometry, 1095 can work well across a variety of edge angles.

For hunting and outdoor fixed blades, the maker may choose geometry that prioritizes durability over extremely fine slicing.

One benefit of 1095 is that it is generally easier to maintain than many highly wear-resistant steels.

The tradeoff is corrosion resistance.

After sharpening:

1. Remove sharpening residue.

2. Clean the blade.

3. Dry it completely.

4. Apply appropriate corrosion protection if needed.

Sharpening D2 Steel

D2 is known for wear resistance.

That can contribute to useful edge retention, but it may also make sharpening slower than simpler carbon steel.

Diamond abrasives can be helpful.

With D2, angle consistency becomes especially important because unnecessary reprofiling can require removing a considerable amount of wear-resistant steel.

Instead of immediately changing the edge angle, try to match the existing bevel first.

Sharpening Damascus Steel

Damascus steel does not require one unique sharpening angle.

The appropriate angle depends on:

• Steels used

• Heat treatment

• Blade geometry

• Intended use

A Damascus Bowie may use a wider edge than a Damascus chef knife.

A Damascus skinner may use a thinner edge than a heavy outdoor blade.

The visible layered pattern does not determine sharpening geometry.

Treat the Damascus blade according to the actual knife design.

Does HRC Affect Sharpening Angle?

Hardness can influence how well an edge resists deformation.

But HRC does not tell you the ideal angle by itself.

A knife at 60 HRC may still require different geometry from another knife at 60 HRC if they use different steels.

Hardness, toughness, and blade geometry all interact.

A higher-HRC steel may support a thin edge in some designs, but the steel must also have sufficient toughness.

Do not choose sharpening angle based on HRC alone.

Sharpening Angle vs Blade Grind

This is one of the most important distinctions in knife maintenance.

Blade grind describes the larger geometry of the blade.

Sharpening angle describes the geometry of the final cutting edge.

Common grinds include:

• Flat grind

• Hollow grind

• Saber grind

• Convex grind

• Scandi grind

A flat-ground knife may still have a 20° secondary edge.

A saber-ground knife can also have a 20° secondary edge.

The main grind and final edge angle are separate.

Flat Grind Sharpening

Flat-ground knives usually use a clearly visible secondary edge bevel.

In that case, sharpen the existing bevel rather than laying the entire primary grind against the stone.

Angle consistency matters.

Use light pressure and work until the edge reaches the apex.

Hollow Grind Sharpening

A hollow grind has a concave primary grind.

However, the final edge may still use a normal secondary bevel.

Sharpen the edge bevel—not the entire hollow grind.

Because hollow-ground blades can be thin behind the edge, they may already cut efficiently without requiring an extremely acute sharpening angle.

Saber Grind Sharpening

A saber grind leaves more steel toward the spine.

The final edge is generally sharpened like a normal secondary bevel.

Because these blades can be relatively substantial, the knife may use a slightly wider edge depending on its intended use.

Scandi Grind Sharpening

Scandi grinds require special attention.

Many traditional Scandi knives have a large bevel that runs directly toward the cutting edge.

To preserve the original geometry, that bevel may be laid flat against the sharpening stone.

Adding a secondary bevel changes how the knife cuts.

That does not mean a micro-bevel is always wrong, but it should be a deliberate choice rather than an accident.

Convex Edge Sharpening

Convex edges do not have one perfectly flat bevel.

Instead, the geometry curves gradually toward the edge.

They are often maintained with:

• Flexible abrasives

• Leather-backed abrasive systems

• Stropping techniques

• Controlled sharpening that preserves the curve

Trying to force a convex edge into one flat angle can alter the original geometry.

How Do You Find Your Knife's Existing Sharpening Angle?

One of the easiest methods is the marker method.

Color the existing edge bevel with a marker.

Then take a very light sharpening pass.

Look at where the marker disappears.

Marker Removed Near the Edge Only

Your angle may be too steep.

Lower the spine slightly.

Marker Removed Near the Shoulder Only

Your angle may be too shallow.

Raise the spine slightly.

Marker Removed Across the Entire Bevel

You are close to matching the existing angle.

This method can help you preserve the maker's original edge without guessing.

Should You Change the Factory Edge Angle?

Usually, not immediately.

If the knife already cuts well and the edge is appropriate for its intended use, maintaining the existing bevel is normally the simplest option.

Changing the angle is called reprofiling.

Reprofiling removes significantly more steel than ordinary sharpening.

You may consider changing the angle if:

• You want more cutting efficiency

• You want greater edge durability

• The existing bevel is inconsistent

• The knife's use has changed

• You understand the tradeoffs

Otherwise, simply maintain the existing geometry.

What Happens If You Sharpen Too Low?

A very acute angle creates a thin edge.

This may improve cutting performance, but the edge can become less stable.

Depending on steel and use, the edge may:

• Roll

• Chip

• Deform

• Require more frequent repair

A lower angle works best when the blade steel, hardness, geometry, and intended use support it.

What Happens If You Sharpen Too High?

A very wide angle leaves more steel behind the edge.

The edge may become durable, but cutting performance can suffer.

You may notice:

• Increased cutting resistance

• More wedging

• Less efficient slicing

• Knife feels dull even when the apex is sharp

A wide edge is not necessarily dull.

It simply has thicker geometry.

Sharpness vs Edge Geometry

A knife can be technically sharp but still cut poorly.

Why?

Because sharpness describes the apex.

Cutting performance depends on the entire geometry behind that apex.

A very thick blade with a polished sharp edge may still wedge through material.

A thinner blade with appropriate edge geometry may slice much more efficiently.

This is why sharpening should never focus only on making the very edge sharp.

What Is an Included Edge Angle?

The included angle is the total angle created by both sides of a double-bevel edge.

For example:

• 15 DPS = approximately 30° included

• 20 DPS = approximately 40° included

• 25 DPS = approximately 50° included

Most sharpening guides use degrees per side because that is easier to reproduce while sharpening.

Is 15 Degrees Too Sharp for a Hunting Knife?

It can be too acute for some hunting knives.

A thin skinning blade in suitable steel may tolerate relatively narrow geometry.

A thick outdoor hunting knife intended for more demanding work may benefit from a wider edge.

Never choose 15 DPS simply because it sounds sharper.

The knife's design needs to support it.

Is 20 Degrees Good for a Hunting Knife?

Around 20 degrees per side is a common general-purpose reference point.

It can provide useful cutting performance while leaving more edge support than a very acute bevel.

For many hunting knives, starting close to the existing 20-ish degree bevel is reasonable.

But inspect the knife rather than assuming every hunting blade was made at exactly 20°.

Is 25 Degrees Too Much?

Not necessarily.

A rugged outdoor knife may intentionally use a wider edge for additional stability.

A 25 DPS edge can make sense on some substantial hunting, survival, or camp blades.

However, that same angle may feel unnecessarily thick on a fine skinner.

Purpose determines whether the angle makes sense.

Single Bevel vs Double Bevel

Most Western hunting, Bowie, outdoor, and EDC knives are double bevel.

That means both sides of the edge are sharpened.

Some specialized knives use single-bevel geometry.

Do not automatically sharpen both sides equally if your knife was designed with an asymmetric or single bevel.

Identify the edge geometry before sharpening.

Micro-Bevels Explained

A micro-bevel is a tiny secondary edge added at a slightly wider angle.

For example, a blade may have relatively thin primary edge geometry with a very small wider bevel at the apex.

Possible benefits include:

• Increased edge stability

• Faster maintenance

• Reduced need to sharpen the entire bevel

Micro-bevels are common in some knife designs and sharpening systems.

They are another reason the visible sharpening angle may not tell the entire story.

What Grit Should You Use?

Angle is only one part of sharpening.

Abrasive grit matters too.

Coarse Grit

Useful for:

• Damaged edges

• Chips

• Reprofiling

• Very dull knives

Medium Grit

Useful for:

• Normal sharpening

• Establishing a clean edge

• General maintenance

Fine Grit

Useful for:

• Refining the edge

• Polishing

• Finishing

Strop

Useful for:

• Burr removal

• Final refinement

• Light maintenance

Avoid starting with extremely coarse abrasives if the knife only needs a minor touch-up.

Sharpening Angle and the Burr

As you sharpen one side of the knife, a small burr can form along the opposite side.

The burr indicates that your sharpening has reached the edge apex.

Once a consistent burr develops, switch sides.

Then use lighter alternating passes to reduce and remove the burr.

The exact method depends on:

• Steel

• Sharpening system

• Grit

• Edge geometry

But burr control is a fundamental part of sharpening.

How Much Pressure Should You Use?

Usually less than beginners expect.

Heavy pressure can:

• Remove unnecessary steel

• Make angle control more difficult

• Increase burr size

• Cause uneven sharpening

Start with moderate or light pressure.

As the edge becomes refined, reduce pressure further.

Consistency is more important than force.

Common Knife Sharpening Angle Mistakes

Changing Angle During Every Stroke

This rounds the bevel instead of creating a clean edge.

Choosing an Angle From a Chart Without Checking the Knife

Charts provide references, not exact factory specifications.

Reprofiling Every Time You Sharpen

Normal sharpening should not require major steel removal.

Using Too Much Pressure

Let the abrasive do the work.

Ignoring the Tip

The sharpening angle often changes accidentally near the tip.

Forgetting About the Burr

A polished bevel does not guarantee a clean apex.

Going Too Fine Too Soon

Fine stones cannot efficiently repair major edge damage.

How Often Should You Sharpen?

There is no fixed schedule.

Sharpen based on performance.

A knife that receives frequent use may require more regular edge maintenance.

A collector Bowie may rarely need sharpening.

A hunting knife may need attention after field use.

An EDC blade cutting cardboard every day may dull faster than a lightly used outdoor knife.

Regular light maintenance usually removes less steel than waiting until the knife becomes extremely dull.

Handmade Knives and Sharpening Angles

Handmade knives may use edge geometry selected specifically by the maker.

That geometry is part of the knife's design.

A handmade fixed blade may combine:

• Particular steel

• Specific HRC

• Custom grind

• Hand-finished edge

• Blade thickness selected for purpose

Before changing the angle dramatically, understand what the maker intended.

Handmade knife performance comes from the entire combination of materials and geometry.

For more about that craftsmanship, read The Art of the Forge: What Makes a Hand-Forged Knife Special?.

What Angle Should You Use? A Simple Guide

If you are uncertain, use this order:

1. Identify the Existing Bevel

Try to match the angle already on the knife.

2. Consider the Knife's Purpose

Fine slicing needs differ from rugged outdoor use.

3. Consider the Steel

Hardness, toughness, and wear resistance matter.

4. Consider Blade Thickness

A thick blade already has substantial geometry behind the edge.

5. Change the Angle Only If Necessary

Do not reprofile just because a chart recommends a different number.

Knife Sharpening at Woodsman Forge

At Woodsman Forge, sharpening is part of understanding the complete knife.

A blade is more than its steel.

The final cutting performance comes from:

steel + heat treatment + grind + blade thickness + edge geometry + sharpening angle.

A 1095 hunting knife, D2 EDC fixed blade, Damascus Bowie, and bushcraft knife may all benefit from different sharpening approaches.

The best angle is not the lowest number.

It is the angle that matches the knife's construction and intended use.

For more help comparing steel before choosing your sharpening approach, read our 1095 vs D2 vs Damascus Steel guide.

Frequently Asked Questions

What is the best knife sharpening angle?

There is no universal best angle. Many knives fall somewhere between roughly 15 and 25 degrees per side, but the correct angle depends on steel, geometry, thickness, and intended use.

What angle should I sharpen a hunting knife?

Many hunting knives use approximately 18–25 degrees per side. A general-purpose hunting knife may fall around 20–22 degrees per side, but matching the existing bevel is usually the best starting point.

Is 20 degrees a good knife sharpening angle?

Yes, 20 degrees per side is a common general-purpose reference for many utility, EDC, and hunting knives. Whether it is ideal depends on the specific blade.

What angle should a Bowie knife be sharpened at?

Many Bowie knives can work well around 20–25 degrees per side, depending on steel, blade thickness, grind, and intended use.

What angle should I sharpen an EDC knife?

A general range of around 17–22 degrees per side can work for many EDC knives. Thinner utility blades may use a narrower edge, while thicker outdoor EDC blades may use a wider one.

Is a lower sharpening angle sharper?

A lower angle generally produces thinner cutting geometry and lower cutting resistance, but it also leaves less steel supporting the edge.

Is a higher angle stronger?

A higher sharpening angle generally leaves more steel behind the edge, which can improve edge stability. It can also increase cutting resistance.

Should I match the factory sharpening angle?

Usually, yes. Matching the existing bevel preserves the knife's geometry and removes less steel than completely reprofiling the edge.

How can I find my knife's sharpening angle?

One simple method is the marker test. Color the edge bevel, take a few very light sharpening passes, and adjust the angle until the marker is removed evenly across the bevel.

Does knife steel affect sharpening angle?

Yes. Steel toughness, hardness, heat treatment, wear resistance, blade thickness, and intended use all influence what edge geometry is appropriate.
