Best Police Knife — Tactical Blades for Law Enforcement

Last Updated: by Aiden Williams

A tactical knife is always a good self-defense alternative when confronting a suspect.

A tactical police knife offers several advantages over other types of edged weapons. It fits nicely into your pocket, it clips in place for added securing, it’s easy to deploy, and snaps open easily with a flick of the thumb.

The choice of the best police knife isn’t huge out there, and you probably don’t know which model is best suited for your particular combat and self-defense skills.

So, in my top four selections, I took into consideration all the important tactical and combat features you would want a law enforcement knife to have.

The KA-BAR TDI Law Enforcement Straight Edge Knife is the most liked and a bestseller because of its unique tactical design that is extremely easy to wheel and control when fighting off a suspect in close-quarter encounters.

Specs

  • 5-5/8-inch overall length
  • 3-11/16-inch blade length
  • Zytel handle
  • Stainless steel blade

The KA-BAR TDI full tang fixed blade knife weighs in at just about 3.2 ounces, which is great because it provides you with a compact model that’s easy to carry on you.

Made from corrosion resistance and edge holding stainless steel, the sturdy tanto point blade is built for tactical, combat, and self-defense with its superior stabbing power.

I really appreciate the unique curved design with a deep finger groove and an ergonomic finger guard that allows you to choke the knife for maximum handgrip power.

The Zytel handle is well-balanced and textured for a non-slip hand placement in both wet and dry conditions.

Pros

  • Compact, easy to conceal, and easy to deploy
  • Comes razor sharp out of the box for self-defense
  • Curved design improves maneuverability during combat
  • Zytel handle offers an incredibly strong hand grip power
  • Deep finger guard and groove improves control of the knife

Cons

2. Smith & Wesson Military & Police M.A.G.I.C Knife – Best Automatic Knife for Law Enforcement

Smith & Wesson Military & Police M.A.G.I.C. Assisted Opening Liner Lock Folding Knife Partially Serrated

Razor sharp and ready for tactical use in law enforcement, the Smith & Wesson Military & Police M.A.G.I.C Knife features a rugged and high performing 3.4-inch blade.

Specs

  • 7-inch overall length
  • 4-inch blade length
  • 4034 stainless steel blade
  • Aluminum handle slabs
  • A.G.I.C opening action

This tactical, military, and police model sports a 4034 stainless steel blade, which is great because it has good edge retention and a high chromium level for great corrosion resistance.

I really appreciate the M.A.G.I.C opening technology, which requires a slight pull of the lever on the spine for the blade to open automatically. This tactical model comes with a rugged tanto blade that is inventively crafted for piercing, slicing and cutting when taking down a suspect.

The blade folds into black colored aluminum handle slabs with rubber inserts, texturing, and grooving, which provide a strong and non-slip hand grip.

The only problem is that the tip-up pocket carry clip isn’t ambidextrous. So, you must make sure that you get your handedness right.

Pros

  • Tactical tanto blade is great for stabbing and piercing
  • A.G.I.C opening action is blazing fast
  • Superior texturing and grooving for strong gripping power
  • Upper part of the blade is serrated for added versatility

The Spyderco Police Model Signature is one of the most tactically ready folding knives ever created. It isn’t too big and not too small, but just the perfect size for law enhancement.

The 4-1/8-inch blade is crafted from heavy-duty VG-10 steel, which is great because it provides you with the corrosion resistance of stainless steel and hardness of carbon steel. The blade is housed within a premium stainless steel handle with beveled edges for superior hand grip and maximum comfort during combat.

What I really appreciate is the well-made back lock system, considering that it is integrated with a Boye Dent for averting any accidental lock release during combat with an offender.

The hollow ground blade has an unsharpened chamfer for acute point geometry and a partially serrated edge for sawing and ripping.

What I don’t like; however, about this knife is the lack of texturing or grooving on the handle.

Pros

  • Blade steel used has good edge retention
  • Combination edge blade is great for combat
  • Beveled edges on the handle improve comfort

Buying Guide: Things To Look For When Buying A Police Knife

A police knife is no ordinary tool, and your conventional knife designs won’t suffice in a do or die self-defense situation against a suspect. So, you need the best police knife integrated with tactical and versatile features.

You need to take into account the following factors to find the right model:

Fixed or Folding Blade

The best law enforcement knife can essentially be one of two types: fixed blade or folding. The advantages of a fixed blade tactical police knife include quick deployment and superior strength.

The benefit of a folding police knife is that it is easier to conceal, making it the best choice for a surprise attack.

Blade Type/Material

Just about any kind of steel can be used to make a knife that is suitable for self-defense in law enforcement. However, fighting is not all there is to survival.

You never know when you might need the knife in an event of an accident or to rescue someone when you are the first responder. So, choose a blade that is forged from a heavy-duty blade steel.

The best law enforcement knife is one that has good edge retention and unwavering wear and corrosion resistance. I recommend stainless steel and high carbon stainless steel blades.

Ergonomics Of The Knife

The best law enforcement knife will always have great ergonomics. Your knife should feel natural in your hand. It should be light, and the handle should have texturing and curves that contour to the shape of your grip. The handle material should be impervious to moisture for a non-slip grip.

Locking Mechanism

The best police knife with a folding design you choose should have a steadfast lock mechanism that is strong enough to prevent the blade from folding when you are trying to incapacitate a suspect.

Also, the lock shouldn’t be too stiff when folding the blade into the handle.

Some of the strongest and safest lock mechanisms you can consider are:

  • A.G.I.C lock
  • Back lock
  • Liner lock
  • Frame lock
  • Tri-Ad lock
  • Axis lock

Final Thoughts

This marks the end of our roundup and we have a winner, the KA-BAR TDI Law Enforcement Straight Edge Knife.

It is a uniquely crafted fixed blade tactical knife with an ingenious curved design that’s extremely easy to maneuver in close-quarter encounters with a suspect.

The AUS 8A stainless steel blade is exceptionally strong with a razor sharp edge and great rust resistance. The drop point tip is just perfect for stabbing in close proximity.

The ergonomic Zytel handle scales are impervious to moisture, making them ideal for sweaty hands. The finger guard adds protection and also improves gripping power.
