This is Mayhew Tools 21500 Extra Long Pin Punch from Mayhew Tools, forged from hardened steel and finished to resist corrosion. The punches and chisels are tempered to take repeated hammer blows without mushrooming prematurely.
It belongs on the automotive, fabrication, or machine-shop bench for driving pins, aligning holes, cutting metal, and knocking out bearings and races. The set keeps the right size within reach for each job.
Mayhew has forged punches, chisels, and pry tools in Massachusetts since 1856, one of the oldest American striking-tool makers.
