Using our Blade Assist Technology, the RX300 Knife is incredibly fast and easy to open and get to work. It combines a liner lock with our Max Lock System to make sure you can comfortably use your knife without it accidentally closing and also be sure it won’t open in your pocket. It has a textured fiberglass filled nylon handle with inserts to quickly move the pocket clip between 3 different locations for your carry preference.

With Coast’s commitment to quality, the RX300 Knife is backed by Coast’s lifetime warranty against defects in materials and workmanship.


From closed to open in a flash. Knives with COAST’s Blade Assist mechanism use a proprietary opening mechanism to release the knife blade faster, smoother, and more safely than other blade-assist systems on the market. Operating Blade Assist is as simple as gently push the studs on the side of the blade until it pops open. Only available on knives equipped with Max-Lock.


Take safety to the extreme. COAST knives equipped with the Max-Lock system can lock the blade in either the open or closed position. Locking the blade closed prevents the assisted opening mechanism from accidentally engaging in your pocket. Locking the blade open protects your fingers from an accidental closure during use. Knives with Max-Lock also have a standard Liner-Lock to make the knives twice as safe.


Carry your knife how it suits you best. Use COAST’s Three Position Knife Clip to adjust the pocket clip to how wear the knife, with easy access to your dominant hand.


Open the knife with a quick flick. Small studs mounted on each side of the knife blade allow for easy, one-handed opening.
