Tool-Steel – A Concise Handbook on Tool-Steel in General – Its Treatment in the Operations of Forging, Annealing, Hardening, Tempering and the Appliances Therefor 

This vintage book contains a comprehensive handbook on the treatment of tool-steel in forging, annealing, hardening, tempering, etc. Profusely illustrated and full of useful, timeless information, this volume will be of considerable utility to those with an interest in metal work and the manufacturing of steel. Many vintage books such as this are increasingly scarce and expensive. We are republishing this volume now in an affordable, modern edition complete with a specially commissioned new introduction on metal work. First published in 1902.
