The combat knife is one of the most used weapons in the history of mankind, in all eras. The initial design of the best combat knife was in the shape and form of a dagger, with a distinctive, razor-sharp double edged blade, excellent for fighting. It was basically a shorter version of a sword, and it was used mostly for stabbing the adversary and as an armor piercing device. Even if the best combat knife was initially used for actual hand-to-hand combat by the military, in the modern day, the best combat knife represents primary a surviving tool and it is widely regarded as a secondary, tactical weapon.


The best combat knife should possess a number of “must-have” features:



  1. First, if you are a soldier, you should go for a fixed blade. Folders are nice and comfortable to carry around, but there are too many things that can go wrong in a mechanism. You don’t want to take chances in the field of battle.

  2. The blade length is an important factor, because the knife must not get in the way yet it should not be too small either; the optimum blade length in the best combat knife is from 5½ to 7½ inches.

  3. The blade thickness of the combat knife must be considered in the equation; the thicker the blade the stronger/more durable it will be, it’s a no brainer. A good blade is at least 3/16″ thick, and if you don’t mind the extra weight, you can go for a 1/4″.

  4. Blade finish is crucial, you need a dark colored/satin finished blade which doesn’t reflects light in a combat situation.

  5. A serrated blade will perform better than a plain one in a multitude of tasks if you will also use your combat knife as a tool, and you probably will. Be aware that a single-edged blade is better than a double edged one when cutting wood, carving etc.

  6. The best material for combat guards is stainless steel and it must have the same color as the blade, it must not reflect light. Keep in mind that the knife’s sheath doesn’t cover the guard, so this anti-glare aspect is crucial. You should keep away from a full double guard, it’s impractical, the best type is the single/one and a half.

  7. The handle of the best combat knife must not crack, shrink or absorb any liquids. The only thing it must absorb is shocks/vibrations. The best handle materials in a combat knife are G10 or linen Micarta. Obviously, the handle should have the same color as the blade/guard and it must not reflect light. You have to make sure that he handle fits your hand perfectly, and it’s not too short or too long or slippery when wet.

  8. The sheath of the best combat knife must attach to your body in such a way that it doesn’t make noises when you’re moving or when you draw the knife. But in the same time, it must not obstruct your movement in any way. The best materials for a sheath are nylon and Kydex, the ideal sheath is made of nylon with Kydex insertions.
