Moulding tools are forged as near to thecorrect shape as possible, afterwards being ground. To harden, heat the cutting edge about three-fourthsof an inch back, enough to harden, according to theshape, but dip deep in the bath and draw the temperto a light straw color. For finishing tools, it is notnecessary to draw any temper with the exception ofthe extreme corners, as indicated by dotted line offigure, which should be drawn to a light straw byholding over the fire. TOOLSMITH AND STEELWORKER 145 Dressing Tools with the Cutting Edge Beveled from One Side Only. When dressing tools of this description a great dif-ficulty is to be contended with, such as hammeringor forging equally from both sides. Most blacksmithsand tool dressers have a great tendency to hammeron the beveled side only, which is a great , for example, sto
