Claim:
1. A lock pin setting system for setting rotational orientations of pins of a lock, the system comprising: a lock utilizing pin sliding and pin rotation by a key that is correctly bitted to correctly operate the lock, the lock having a plug defining a keyway and a plurality of bores positioned along and extending from the keyway, the lock including a bottom pin positioned in each of the bores and being slidable and rotatable with respect to the bore, each of the bottom pins having a contact surface permitting the bottom pin to be rotated in the bore by contact with a bitting surface of the correctly-bitted key, each pin being configured to be aligned with a shear line of the plug when contacting one of the bitting surfaces located at a plurality of bitting depths, the plurality of bitting depths for the correctly-bitted key being predefined so the key is able to correctly operate the lock by moving the bottom pins to alignment with the shear line, the plurality of predefined bitting depths capable of moving the bottom pins to the shear line ranging from a predefined highest bitting depth of 1 to a predefined lowest bitting depth of 6 with multiple bitting depths between 1 and 6, each of the predefined bitting depths being separated by a uniform depth increment; a lock pin setting tool comprising:
