Using Coast's 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.Max-LockThe Max-Lock System is a unique and independent locking system that can lock the blade both in the open and closed position by engaging a metal bar into a riveted stainless steel washer in the blade. Locking in the closed position keeps the assisted opening mechanism from accidentally engaging in your pocket and locking in the open position gives you reassurance that it wont close on your hand. Knives with Max-Lock also have a standard Liner-Lock to make these twice as safe.To operate the Max-Lock switch, simply push the switch forward to lock the blade and expose the "lock" icon or pull the switch backwards to expose the red mark and allow it to open the blade.Max-Lock (only available with Blade Assist Knives).
