Those teeny-tiny key ring knives can’t do much more than pare your fingernails. But you expect more – and the SOG® Keytron delivers. At a mere 5-3/8" long and just 1.3 oz., it fits comfortably in a front pocket without pulling your pants down. The 1-3/4" clip point blade is engineered of easily sharpened 5Cr13MoV stainless steel. Lock back mechanism prevents accidental knuckle nicks (or worse). But what’s really cool is the locking ring mechanism that contains your keys, clips to a key ring or clamps onto a backpack or tool bag. And when the day’s done, the built-in bottle opener can uncap a celebratory brew.
