Don't poo-poo the canoe. Getting up in years, and my nails are getting brittle. Had a Case canoe that bothered me at first because the spring on the big blade seemed a little weak for a new knife. But I soon found that I could open it with one hand by pinching the big blade between thumb and forefinger and pushing the knife away with the other fingers. I had been carrying a Gerber LST and opening it that way, but the Canoe (now stolen) became my favorite EDC. I have a Boker and some Rough Rider canoes that I can open without using my nails, but not with one hand. I have a huge Boker congress and a medium Case congress on which I can open the big sheepsfoot blade easily with one hand and no nails, but don't carry them much due to thickness. If you don't like canoes, a half-congress might be just the ticket. Go to your local hardware and try a few of each.
