12.9mm firmer chisel is forged from one metal piece from blade to socket tang. This blade thickness tapers from 7mm to infinite. The wood handle is refitted new from a hardwood dowel with a 1mm x 12mm brass metal hoop further cushioned with a leather disc insert. This brass hoop and disc protects the handle from mushrooming when struck with a hammer. A well reconditioned firmer chisel with many more years of service.
