Excerpt from Saw Filing and Management of Saws: A Practical Treatise on Filing, Gumming, Swaging, Hammering and Brazing Band Saws; Speed, Power and Work to Operate Circular Saws, Etc The saving in power, by using a sharp saw, is very great. It has never yet been measured in power-saws, and is hardly measurable in hand-saws; but it is without doubt consider able. By using sharp saws, thinner blades may be used than where the teeth are dull; because the duller the saw the more power required to drive it through the wood, and the more strain on each tooth separately, and on the blade as a whole. For the same reason, longer teeth may be used where they are sharp, than where they are dull. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
