Thought this would be an interesting topic. I'm nearly 26 now and I got my first knife when I was 5 years old, my dad gave me a knockoff of the traditional Buck folding lockback with the brass bolsters and wood inserts. It suffered my 5 year old abuse for a while but after stabbing it into a block of wood one day to do some "carving" the lock bar broke and it folded up on my tender young hands, neatly shearing the end of my pinky nearly off. I still have the scar, because Mom just wrapped a bandaid around the end of it to hold it on there until it healed. Needless to say I didn't get another knife until the Christmas I was 10, my parents bought me another cheap lockback, this time with the message to be careful. I'm still not a fan of lockback knives to this day.
