How to do the one hand draw:
It breaks my heart to see people doing things like filing off the part of the sheath that retains the knife in the sheath because they can't extract the knife. I was on one site where half the reviewers there had butchered the sheath. It is very simple, as simple as snapping your fingers.
Here it is!
Place the face of your thumb on the knife retainer at the top of the sheath and the bottom of the handle. Curl the first finger back under the rear finger guard of the knife. Snap your fingers! Pop! It pops up like jack in the box and lands right in the palm of your hand.
I learned this from a woman after fumbling around with for quite a while!!!! Sometimes....we guys are too smart for our own good! Okay! Okay! I will speak for myself.
