Nor am I.
Once, during a rather heated portion of FOF with Simunitions, I was required to start the scenario on the ground. My opponent was a large man who leapt into the air and landed with his knee on my right shoulder and was putting considerable effort into getting the Sim-Glock out of my right hand. While I was busy emptying the pistol into the wall behind us so he'd have no rounds to use on me, my left hand was desperately trying to access the Spyderco that lived in my left pocket for just such an imagined scenario.
This took place under the watchful eyes of good instructors, to naturally there was no live blade on my person and it was long enough ago that quality training copies of edc knives were not so plentiful and readily available. I wish I'd had one that day as I'd very much have liked to provide that opponent at least a bruised liver or separated rib as thanks for the two breaks I now had in my shoulder. Fwiw, both instructors moved in to stop the scenario immediately and I learned a lot from it.
A decade or so later, I was gifted a waved Spyderco. I swapped the pocket clip to the left side, dropped to my back in open guard and couldn't reliably deploy the folder from that position. Never carried it. At 53, my next knife purchase will probably be a Northman. Welcome to pm me if anyone's got one they're not enamored with.
