![]() ![]() ![]() I do not believe there is a fit allowance (I currently have neither or I would go measure). The tooling for this is expensive so the manufacturers have "standardized" on 1". Old factory hardy shanks that I have measured were as-marked with no allowance for fit.Ī number of modern anvils (Peddinghaus, Nimba.) have drilled and broached hardy holes. There are other makes with metric hardy holes. One of the last makers to use progressive hole sizes is Kohlswa who uses metric sizes. If you wanted a set of tools that fit that 1-3/16 hardy hole you made them. Many old anvils had fairly even sized hardy holes up to 1" (5/8, 3/4, 7/8) but over one inch where various odd sizes that no hardy tools have ever been made to fit. All were sold as X size by what they were supposed to be but most seem to have a little oversize for fit. Cast holes are more uniform but cores often have burn-in and end up with ugly obstructions or rough areas protruding into the hole. Many of the punched hardy holes were crooked, diamond shaped, tapered. ![]() Until the Modern Era (After Mousehole, Hay-Budden, Fisher Etal) almost every size anvil had a different hardy hole size. Later they were moved to the center line at the heel of English and American anvils and just at the horn on most European anvils. In early anvils the hardie hole was only about 1/2" square and sometimes placed at the side of the face of the anvil with the bottom curving out of the side of the anvil. These include, "bottom sets" with round grooves that match handled "top sets", fullers, forming tools and anything else the blacksmith finds convenient to put a square shank on to be supported on the anvil. Other tools with square shanks are also used in the hardie hole and are sometimes called "hardie tools". The hardy, or hardie, hole is the square hole in the top of a blacksmiths anvil designed to receive tooling such as a hardie.Ī hardie is a short heavy chisel that has a shoulder and a square shank to fit the square hole of the anvil.
