The Coast RX322 Blade Assist Tanto Blade Knife is a very specially designed knife for its blade assist technology. This Knife by Coast with its stainless steel frame and nylon filled nylon handle add incredible strength and durability, was designed by world class custom knife maker and inventor, Ron Lake. The Coast RX322 Blade Assist Tanto Blade Knife w/ Stainless Steel Frame uses a patented system using a roller-bearing mounted to the blade and a leaf spring mounted between the handle liners resulting in a blade that releases faster, smoother, and safer than other assisted opening knives on the market. The Coast RX322 Blade Assist Tanto Blade Knife w/ Nylon Handle features thumb studs on both sides of the blade and thumb ramping on both sides of the handle make firing the blade easy from right or left side carry positions. A reversible, stainless steel pocket clip is included making the knife fully ambidextrous. The Coast RX322 Blade Assist Tanto Blade Folding Knife w/ Max-Lock uses Coast's patented Max-Lock technology which provides a second lock system. This safeguard secures the blade closed when not in use and double locks the Liner-Lock when open, even if the Liner Lock is inadvertently dis-engaged, preventing disastrous accidents from happening.
