1/2″ socket firmer chisel, marked “Edge Tool Works”

Description

Possibly a product of the Underhill Edge Tool Works of Nashua, NH, but that’s just a guess.  It’s clearly a quality tool.  Handle’s old enough to be original, but might be a re-fit — there’s some mushrooming around the socket, and the handle’s a little lightweight for a chisel this size.   About 7″ left to the shoulder.  Frosted; needs a lapping but you’d do that anyway.
