WHEELER ENGINEERING F.A.T. WRENCH The ratchet-slip F.A.T. Wrench easily adjusts from 10 to 70 inch-pounds, with the setting shown in a window in the handle. The wrench comes with an adapter for hex shank bits and includes a small assortment of gunsmithing bits, plus a list of recommended torque settings for different types of gun- and scope-mounting screws.

BROWNELLS MASTER SET WITH BENCH BLOCK This set comes with 20 screwdrivers with hollow ground blades. The semi-short shank lengths are ideal for good control, with each shank being the diameter of the blade so it can be sharpened or reshaped as needed. The oak bench block, which stores the screwdrivers upright for easy access, is extra. (Set, $149; block, $76; brownells.com)
