These chisels have comfortable perfect-pattern handles cast of 420 stainless steel that are double-scarf welded to 440 stainless-steel blades of Rc56-59 hardness. The handle scales of resin-impregnated pakka wood are brass-riveted in place and the entire handle and neck are then hand polished. The 7-1/2" long chisels come in 1" (25mm), 3/4" (19mm), 1/2" (13mm), 3/8" (10mm) and 1/4" (6mm) widths. The set comes with snug-fitting tip guards in a fitted presentation box. A pleasure to use and a wonderful gift.
