To make it truly foolproof, make sure to clamp the knife down. Everybody does stupid things without thinking about it, and I'm not ashamed to admit I've tried to work on knives thinking I could hold them steady without problems. I am lucky enough not to have cut myself, but I did slip and put a scratch in a handle scale that I shouldn't have.
And put some masking tape on the lock openings and wedge a piece of moist paper towel in between the two scales to avoid any of the dust fouling the lock.
