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 guarantee against defects in materials and workmanship.
