When I was 8, the measure of a good folder was how many tools and blades it could unfold. It's not like I ever needed a corkscrew or a pair of mini scissors, but by God, if a knife didn't have those, what good was it? If I were to get a boy a knife, it would have at least a dozen "functions!"
The trouble with the Swiss Army Knife and similar folders is that they don't lock. The closest I ever came and the closest I ever saw any other Cub Scout come to hurting himself was having the knife close on the fingers. Never actually happened as a kid, but I came so close to that happening as a teenager. I had some super sharp Uncle Henry (might have been a Boker) or something more than 15 years ago that didn't lock. Man, I came close to cutting myself once with it that way. I thought about actually getting rid of it. Then, one night, I handed it to a friend. I explicitly warned him that it didn't lock and to be careful it didn't eat a finger. Well, we had to go to the ER. Blood everywhere. He was turning white.
I walked outside and threw the knife across the road into the woods right then and there. Probably still laying out there.
He still brings that up every now and again. Anytime I hand him a knife, more than 15 years later, we chuckle.
