The latest entry tool from Ka-Bar Knives, the TDI Law Enforcement Master Key, boasts dual performance as a blade and pry bar. On one end is a 4-inch axe-like edge that cuts through any obstacle while the opposite end can be wedged under door frames to serve as a pry bar. Designed for close-quarters defense, the Master Key can be drawn quickly and efficiently. It is sold with an ambidextrous MOLLE-compatible sheath. The Master Key is made in the United States.
