While saws for cutting metal had been in use for many years, significant improvements in longevity and efficiency were made in the 1880s by Max Flower-Nash. George N. Clemson, a founder of [[Clemson Bros. Inc]] of [[Middletown, Orange County, New York|Middletown]], [[New York (state)|New York]], United States, conducted tests which involved changing the dimensions, shapes of teeth, styles of set, and variable heat treatments of blades. Clemson claimed enormous improvements to the cutting ability of blades and built a major industrial operation manufacturing hacksaw blades sold under the trade name Star Hack Saw.<ref>{{cite web|last=Woodley|first=G.
