The KA-BAR TDI Last Ditch 1478BP is the ultimate deep-concealment backup tool. John Benner of the Tactical Defense Institute designed this diminutive fixed blade to be totally unobtrusive until absolutely needed. Consequently, it can be secreted anywhere on your person, from inside a boot to behind a duty belt.
Specifically, the skeletal design of the KA-BAR TDI Last Ditch keeps the weight under an ounce while maintaining critical strength. It is crafted from corrosion-resistant 9Cr18 stainless steel. It includes a hard plastic friction-fit sheath that can be laced into boots, worn around the neck, or strapped to a vest.
