If I may add, I feel the best time to convert non knife people over is when they realize they could use a knife
My favorite example of this was on a bike ride. I was on a rail trail and I found a lady on the side trying to fix her bike. An earphone cord had tangled and jammed her crank so she could not peddle. I asked if she would like help and of course she did being miles away from her car. I pulled out an OP6 with the blade black from food prep work. The lady seemed scared of the knife even as tiny as it is...until the thin blade barely cleared the tiny gap to access the cord and cut it in two. I pulled out the cord and she was extremely thankful.
She went on to explain how she has never liked knives but now she can see why someone would carry a pen knife. She was amazed to hear the price of an OP6 also
