    Isn't this a little dangerous? These knives' lock mechanism is mostly flimsy and gets broken easily. When cutting hard stuff such as corrugated cardboard the lock starts to slip on the rack. The blade may suddenly retract when it happens if it is spring loaded, and cut the user's hand. I suggest doing this only with sturdy box cutters with a metal lock mechanism.
