Conceived specifically for rescue personnel, the DX330 has a partially serrated tanto blade which will power through the toughest cutting job with ease. A glass breaker and integrated seatbelt cutter are included for maximum versatility. The knife features a patented Double-Lock safety switch mechanism which works in conjunction with the primary Liner-Lock to prevent disengagement when the knife is open, even if the Liner Lock is inadvertently dis-engaged. A grip-textured aluminum handle adds incredible strength and durability. Thumb studs on both sides of the blade make opening the blade easy, right or left handed. Backed by Coast's lifetime warranty against defects in materials and workmanship.
