Round 6" Long No. 4 Cut Key File - Swiss Made
For locksmiths looking for the ultra smooth and slower progression in a lock file, the No. 4 cut is the choice for you. Finer than the number 2 finish, the number 4 lock file gives a smoother finish and removes less material with each stroke. Locksmiths that are prone to removing too much material when impressioning locks may enjoy this tool. The round design is a great choice for the number 4 lock file as it tends to clog or fill up the tool a bit faster because of the finer pattern. The round shape provides more surface area for longer clean out intervals than other designs.
