Buying cheap crap so you don't mind if you lose it is nuts. If it is incapable of doing the job it is intended for, you might as well not have it.
Pro mechanics don't buy snap on because they can get a free replacement if it breaks, they buy them because they are pretty well assured they WON'T break.
A knife is basic tool #1, first on the list, neolithic to modern day. I remember my first- on my 8th birthday Dad brought me to the hardware store and I picked out a nice bone handled three blade stock-mans knife.
I was so proud of that knife. I had it for about 4 hours- a bunch of kids and I were playing football in the yard, and after the game the knife was gone from my pocket. I scoured the yard- no knife- one of the other boys must have "finders keepers" it. My sob story to my dad elicited no sympathy. No replacement was forthcoming. It was a good lesson.
Amazingly few people , especially kids, carry a knife anymore. Baffles me. I think they "learn" that in school.
