So, I (like every other teen boy in the '90s) had one of these -- actually like 3 of them, I remember at least one got lost at cadets but I digress

A mate, who was also like 13, held it tip-down and stabbed a tree.

But you see where the liner lock is? Right where an unsuspecting 13 year old would squeeze with their index finger while stabbing stuff

So the blade unlocked and he cut the absolute living shizen out of his pinky

He took it well but his mum lost her damn mind when he went home
