I hope to never participate in a knife fight. I no more regard my knife as a weapon against another human than I do my hatchet, even though either could be used as such.

One of the uses I envision for a one handed opening knife is a fall from a deerstand. Deerhuntig is a somewhat solitary activity, and an elevated stand is used in snowy conditions when wearing baggy cloths for protection from the very cold Nov-Dec weather. Deerstands have cables, bolts, various metal supports, ladders, and platforms on them. There are also nylon safety harnesses that many use to prevent a fall to the ground. I could see a person slipping and falling to end up dangling by a strap, a bootlace, or pant leg etc.

It would be a great advantage to have a good one-handed knife within reach to cut oneself down. I would not risk my safety on a modification.
