A tough, carbide glassbreaker and partially serrated edge make this a must-have emergency tool. The carbide glassbreaker is key; a plain steel tip won’t have the same effect in an emergency. To break out a windshield and pull a victim to freedom, it’s got to be carbide. The Blur’s big, multitasking blade makes it an even more effective rescue tool. Built of high-performance 14C28N, the partially serrated blade cuts through seatbelt webbing with ease, which can make all the difference at a crucial moment.
