Study aircraft history, and you find the name Thunderbolt connected both to the P-47 fighter and A-10 fighter bomber. They are both invariably described as "large, rugged, dependable." Those words also fit Ron Lake's locking liner design for the CRKT Thunderbolt™. Briefly, this is a heavy-duty locking liner folder series, with premium blade steel, aircraft aluminum InterFrame build, with a stainless steel clip and our patented LAWKS® safety, all at a fabulously competitive price. The smaller Thunderbolt™ 2 models are ideal for every day carry. Weight is 5.7 oz. and blade length is 3.437". Blades are extremely strong dual-grind Tanto-style with a drop point top edge. Blade steel is 8Cr14MoV high-chromium stainless steel with a special non-reflective black oxide coating. Fast one-hand opening is accomplished by a large oval thumb hole with friction grooves on the outboard edge. Ron Lake has designed a large, ergonomic handle with a center swell and grooved areas at the thumb and pommel. These are knives you can use while wearing gloves and under slippery conditions.
