Description
With a peening jig, any standard hammer about 1lb / 500g in weight can be used. Peening with an anvil requires a more specialized hammer such as this one.
The face of peening hammers must be kept smooth and shiny as any dint or defect in the face of the hammer will be imprinted in the blade being peened. A peening hammer should be reserved for peening with an anvil only and NEVER used with the jig, or worse yet, to hammer in nails!
