If we are out of a Peddinghaus hammer or other tool we will substitute a Picard German equivalent. Often times the difference is cosmetically only or we would not consider it a valid substitution. If you do not want us to substitute please indicate this at checkout under 'Special Notice to us'. The price usually will be the same or less.
The essential part of a hammer is the head, a compact solid mass that is able to deliver the blow to the intended target without itself deforming. The opposite or back side has a ball pein (peen).
As the impact between steel hammer heads and the objects being hit can, and does, create sparks, which in some industries such as underground coal mining with methane gas, or in other hazardous environments containing flammable gases and vapors, can be dangerous and risk igniting the gases. In these environments you should use extreme caution.
