The Rat Worx MRX series of knives represents several firsts in the knife making industry. It features a fully automatic blade that operates on an innovative mini roller chain system. Simply press the firing button and a chain pulls the blade smoothly into the open position with snappy automatic action. The blade is powered by dual nested right and left hand extension springs and pivots on a permanently lubricated ball bearing system.

This MRX model has a recurve blade made from CPM-154 steel with a two-tone satin finish. The lanyard cut handle is made from aluminum with a black hard coat anodized finish and comes equipped with a tip-up carry pocket clip. This MRX line of knives represent the next generation of fail-safe automatics, and are the only knives with a chain link auto mechanism and permanently lubricated ball bearing pivot.

They should have named this knife brand "Tank." It is built tough. The action is good. The spring runs along the spine and connects to the chain. Don't worry about pocket lint clogging the chain. This knife can take anything. Everyone who sees this knife is just in awe of the looks of it. This knife comes razor sharp and locks hard in place. I highly recommend you trying one.
