Kershaw Blur Glass Breaker, 3.4, Assisted Folding Knife, Modified Drop Point, Thumb Stud, Pocket Clip, Glass Breaker, 14C28N/OD, Black Anodized Aluminum 6061-T6 1670GBBLKST The Blur has been a Kershaw favorite for many years. It's the ideal knife for tough use" whether on the job or around the garage. The recurve blade is built for multitasking with excellent slicing and piercing capabilities" and the aircraft aluminum handles are tough and lightweight. This Blur also has a carbide tip built into those durable handles. And that's important because a plain steel tip won't have the same effect in an emergency. If you need to break out a windshield in order to pull a victim to freedom" it's got to be carbide. In the Blur Glassbreaker" it is. The Blur's blade makes it an even more effective rescue tool. Built of high-performance Sandvik 14C28N" the partially serrated blade cuts through seatbelt webbing (or other tough materials) with ease" which can make all the difference at a crucial moment. The Blur Glassbreaker is designed to give you a secure grip" too" even in non-optimal environmental conditions. The handle features Trac-Tec grip tape inserts that provide extra traction to help keep the knife where it belongs-in your hand. The Blur Glassbreaker is equipped with SpeedSafe(R) assisted opening so you can easily open the knife one-handed. Which is also important-because you're not always going to have both hands free in an emergency.
