The Coast DX345 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 stainless steel frame and G10 handle add incredible strength and durability. Thumb studs on both sides of the blade make opening the blade easy; right or left handed. A three position, stainless steel pocket clip is included making the knife easy to carry for daily use. Backed by Coast's lifetime guarantee against defects in materials and workmanship.
