Well; I can hardly believe it; I am putting the Spyderco Endura pocket knife I have carried for about 30 years into semi-retirement.
After reading a story where someone (turned out to be a New Orleans cop but just the same) came up behind a guy open carrying, put his left arm around his neck in a choke hold and seized his sidearm got me thinking, the Spyderco rides great in the right pocket hinge down great for rapid deployment. But if my right hand is occupied securing my sidearm I need something for the left hand.
It is near impossible to find folders that clip hinge down, and have not found a left handed hinge down knife, until yesterday. So if grabbed in a choke hold from behind, the new knife can be deployed with left hand only ready for "Operation Castration". New knife is on the top, out of the box it is scalpel sharp, ready for a little "surgery".
