Highland, correct me here please, but would you really expect (or want) a multi-tool to be able to bust through the lock in your door? About 8 years ago our son, then 4, locked himself in the house and we had to call the cops. They used a big crowbar and still couldn't open the door. (They finally broke a window in the basement.) I mean, I love my Leathermans and maybe you're being a little too demanding?
