I've found most guys are fascinated by autos. But it seems many have a tendancy to use the trigger button to unlock the blade to close it. The guy next door was over, and asked, "What have you got there?" I said, "I just got a new knife." He said, "What do you need 'that' for?" He's not getting his hands on any of my knives.
Several times I've had to yell, "STOP!", when one of my uncles was pressing the deployment button to unlock the blade to close it. Yeah, it's gotta work if you use enough force! He's a guy who grew up on a farm in community where most boys carry a pocket knife to school. I figured he'd use more sense.
Then, my other uncle was opening my Buck 110 Auto, which has a good kick, and it got away from him, so he caught it by the blade! It was ugly. But just the tip went into his hand, so the cut was deeper that it was wide. Didn't need stitches. And he was a rancher for 20 years. How can he not know how to use a knife?
I also have knives I either got for free from a supplier, or that just wore out. I give those away.
