A dinging hammer is a lightweight body hammer with a small round face on one side and a small square face on the other, purpose-built for the lightest, most controlled stage of sheet metal panel work — raising low spots and making fine surface corrections rather than the heavier bumping done earlier in a repair sequence. Unlike a finishing hammer's slightly larger faces meant for smoothing after major shape has been restored, a dinging hammer's smaller faces and lighter overall head weight give the technician finer control for the final touch-up pass.
Auto body technicians and restoration shops rely on dinging hammers wherever a panel needs delicate correction close to trim, moldings, or beading — the square face specifically permits dinging tight against these features where a round-only face would strike the adjacent trim. Martin Tool and Forge's 151-series covers this application with both a long-reach configuration (151G/151FG) for accessing recessed structures like inner quarter panels, door skins, and roof structures, and a short-reach configuration (161FG) for more accessible panel areas.
Common configuration: 1-1/4" round face paired with a 1-1/16" (or 1-11/16" per some listings) square face, 6" overall length on the standard long-reach 151-series, 0.85 lb head-and-handle weight, drop-forged construction, and a choice of traditional wood handle (151G) or cushion-grip fiberglass handle (151FG) — the fiberglass version specifically engineered for a balanced, reduced-fatigue grip during extended professional use. The related 161FG short-reach model uses a similar 1-1/4" round and roughly 1-3/16" square face combination on a shorter 4" overall head length for lighter-duty or more accessible panel work.
