Conceived specifically for rescue personnel, the DX335 has a curved blade designed to easily cut clothing or seatbelts while minimizing the possibility of injury to the rescue victim. 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 knife easy; right or left handed. Backed by Coast"s lifetime guarantee against defects in materials and workmanship.
