The ideal backup weapon for military professionals, meant to be carried on the non-dominant side. Bigger and with more reach than the original TDI. Designed for close combat situations where the firearm isn’t accessible but works in other tactical use as well. The knife is drawn from the sheath just like a pistol from the holster. Usable both in normal and reverse grip.

This knife was designed by John Benner, the founder and owner of Tactical Defense Institute (TDI), hence the name. When the original, more compact model became extremely popular, a whole range was created around it. This is the Large model. This knife has a black-coated blade, handle, sheath, and metal belt clip.

Sheath

The knife comes with a hard plastic sheath with MOLLE-compatible straps. With them, you can attach the knife to the webbing of the battle belt or load-bearing gear. You can also put a regular belt through the straps but especially with narrower belts, it isn't the ideal solution. For regular belts, the straps have separate loops for a max. 38 mm (1.5") belt.

The idea is to carry this knife on the non-dominant side. So the right-handed folks carry it on the left side and the left-handed folks on the right. With the tool that is included, you can move the straps on the other side of the sheath, depending on whether you want the sheath on the left/right or on the inside/outside of the belt.

Use

Ka-Bar TDI Large is meant to be the last resort of soldiers and other professional Action Jacksons. Such a case is when you have to wrestle with the enemy and your gun is stuck in between or someone suddenly tries to grab your gun.

The knife is worn on the non-dominant side either on the inside or outside of the battle belt or regular belt, or on the load-bearing gear. The curved fixed-blade knife is drawn like a pistol. So, you can deploy it a lot faster than a folder. You can also cross-draw it with your dominant hand if needed. The other benefit of the curved design is that you can sit, bend over, and do things comfortably and naturally without being bothered by the knife.

This knife can be used for both slashing and punching, and it works in both regular and reverse grip. AUS 8 is fairly easy to sharpen for being stainless steel.
