Always be prepared with the emergency-ready Drivetrain. For this knife, Kershaw designed a hassle-free seatbelt cutter. It stays within the handle when not in use, but it can be easily deployed without any struggle. When time is of the essence, the handle naturally guides the seatbelt into the cutter, which locks into place with a liner. Kershaw rigorously tested this function to be our best seatbelt cutter yet. As a second option, responders can access the 3.2-inch blade quickly with SpeedSafe assisted opening. For repeated use, its D2 blade steel holds a long-lasting edge. A carbide glass breaker tip breaks car windows with ease, rounding out this responder-friendly tool.
