The Talon series of handmade custom neck knives is very discreet and extra sneaky. The Talon can be carried in many ways. Small enough to fit in the fifth pocket of most jeans or around the neck with the included paracord lanyard. 
Designed to fit under your pointer finger. Quick deployment from the sheath makes this small but mighty slashing tool ideal for everyday carry.
