Maintain Consistent Sharpening Angle

Maintaining a consistent angle is all about the proper degree and keeping it constant throughout. Do you know what your tactical knife's bevel angle should be? Tactical knives have different degrees of angles depending on their manufacturer, so make sure to research yours! It is crucial because it allows for an even wear of the Tactical Knife. This results in less damage to your Tactical knife, and therefore more time before you need to sharpen again. There are many different ways people choose to maintain their bevel angles, but one of the easiest things you can do is place a marker (or two) on both sides of your Tactical Knife at the required degree.

However, if there is any visible chipping on either side of your Tactical Knife, then that means it is time to stop maintaining your Tactical Knife's bevel angle. Make sure you are not over-sharpening as well! Tactical Knives can become extremely sharp. It is easy for the user to go overboard with an overly sharp Tactical knife, which will cause damage to both the Tactical Knife itself and whatever you happen to be cutting.


Common Sharpening Angles (Degrees per Side)

Each knife is designed differently and can be made from various materials. The angle of the blade determines how durable it will become, as well as what food or material you are cutting with your knife. A razor has an acute angle that makes it very sharp and increases its fragility due to a thinner edge being more susceptible to damage on denser foods when slicing through them. Tactical Knives are the opposite, with a thicker edge and more durable material to keep their sharpness longer.

Hunting Knives – 22

The Hunting Tactical Knife is perfect for those who go on long outdoor trips and want to keep a reliable Tactical Knife that will last. The best hunting knives are usually made from steel alloys or carbon-based materials. However, there have been advancements in ceramic blades, which can be even more durable than the average metal blade! The Hunting Knives' angle to sharpen it is to be 22 degrees on both sides of your Hunting Knife.

Sharpening Angle Chart From Manufacturers:

"22+" Angles are not common, but they have been known to exist in the market. These angles are usually very small and can be found anywhere between 15° and 35° per side.

Tactical Knives – 23

Tactical Knife Sharpeners will have an angle at which they sharpen their Tactical Knives depending on what is required for that type of Tactical Knife:

  • Spyderco has 30° per side
  • Kershaw has 20° per side
  • SOG has 17.75° per side

Most Tactical knives can be classified as having either 15 or 25 degrees per side which correspond closely to a double/single-sided beveled blade where one face of the knife (the single) would make contact with the stones when sharpening it. This is vital information to know about your Tactical Knife because it will determine how often you need to sharpen your Tactical Knife and what sharpening tools, like an angle guide, for instance, are best suited for the job.

 In regards to having a fixed or adjustable Tactical Knife Sharpener bevel angles:


Some Tactical Knives with a fixed blade have set degrees per side that permanently align with their blades, so they cannot adjust their bevel at all (i.e., Kershaw Tactical knives). The benefit of this is there's no guesswork involved in maintaining your Tactical Knife's blade from dulling over time - just use it! 


Most other Tactical Knives can adjust their edge by moving a wheel on its spine perpendicularly around its length. Some Tactical Knives also have a folding handle feature.

Custom Knives – Varies by Designer

Custom Knives are Tactical Knife designs that are made from scratch, and therefore have a unique degree per side. For example, Spyderco's "Paramilitary" Tactical Knives have an angle of 35° per side, while their "Endura" Tactical Knives can be anywhere between 15-20 degrees depending on the model type. Even though these angles may seem random in nature, there is actually some logic behind them:

  • Spyderco has 30° for its Paramilitary Tactical knives because they use CPM S30V steel, providing good edge retention at this high sharpness angle compared to other knife steels.
  • Kershaw's 20° Angle was created due to using Sandvik 14C28N Steel which performs better with less acute angles with its increased edge retention.
  • SOG Tactical Knives have an angle of 17.75° per side because S30V steel is used, and it has a high wear resistance which causes the knife to be dull over time. So they recommend frequent sharpening at this lower bevel angle compared to other Tactical Knife blades made from different materials like VG-MAX Steel (used in Columbia River knives).

Sharpening Angle Chart From Manufacturers:

  • "17+" – these angles are usually found on Japanese Tactical Knives that use VG-Max or ZDP 189, AUS metals for their blade steels due to them being harder metal alloys than CPM S30V steels used by Spyderco or Sandvik 14C28N steel used by Kershaw Tactical Knives.
  • "20+" - these angles are usually found on Tactical Knives that have more acute edges compared to Japanese Tactical knives with harder metal alloys due to them having increased edge retention at their respective bevel angles. These knives can still cut well because the sharpness angle is low enough where it doesn't lose its cutting ability yet, not as high an angle as Spydercos' Paramilitary Tactical Knife's 30° per side.


Knife Sharpening Abrasives

Knife sharpening abrasives are used for Tactical Knife sharpening purposes. It is a material with an extremely fine surface texture on it that can be attached to or built into various surfaces (i.e., stones, rods). Different types of knife sharpening abrasives are:

Diamond Sharpener

Diamond abrasive knife sharpeners are very effective and durable. They can remove metal quickly because diamonds are the hardest substance known to man. Diamond sharpening surfaces have a surface that collects and holds the filling, which allows for use with or without honing solution.

Additional Input: Diamonds are typically found in Tactical Knifes' blade steels because they provide the best hardness out of all other materials due to their composition, so they will stay sharper longer than any other metal alloy when it is manufactured into an actual knife by companies like Spyderco & Kershaw. They use S30V steel, which has a high wear resistance rate compared with VG-Max Steel (used in Columbia River knives).

Ceramic Sharpener

The Ceramic sharpening abrasive is unlike other sharpening stones. While it does remove metal, it removes very little of the knife edge and works better as a finishing tool than an everyday stone used to sharpen blades. The color can range from white or blue to black in grits that are labeled coarse or fine. It also comes in different shapes, such as oval or triangular depending on the user's preference.

Ceramic Tactical Knife sharpening abrasives are made from a type of clay that is crushed and then shaped into the desired form. Ceramic Tactical knife sharpeners can very effectively remove metal quickly but don't last as long because ceramic has a lower hardness rating than diamonds do.

A Tactical Knife is a great and useful tool for Tactical, Military, and law enforcement purposes. Tactical Knife blade steels have a high wear resistance which causes the knife to be dull over time, so Tactical Knives manufacturers recommend frequent sharpening. Diamond abrasives are more effective at removing metal than other materials such as ceramic or natural stones. They are hard and can remove metal quickly but don't last as long as ceramic Tactical knives sharpening abrasives.

Proper maintenance of a Tactical Knife includes oiling them after every use (to prevent rust), wiping down any dust or dirt buildup on the blade, keeping your Tactical Knife dry at all times when not in use (e.g., protecting them from water), and applying some form of protection onto your Tactical knives' blades. In case they come into contact with anything that may endanger the Tactical knife's blades, such as moisture, dirt, or rocks. Tactical Knife sharpening abrasives are used for Tactical Knife sharpening purposes and come in various shapes and sizes depending on the Tactical Knife company that manufactures them.
