[Jos Weyers] tipping us off about this lock impressioning video. It shows his final round of the lock impressioning championship at this year’s SSDev conference. Even though he shaved about fifteen seconds off of his 87-second single-lock record from last year he came in third overall because the competition averages times over several rounds.
This method of opening locks uses a file to create the correct teeth after examination of tiny marks on a key blank from trying to open the lock. We’ve seen foil impressioning as well as electronic impressioning, but video of the competitions makes this our favorite method.
