Hyfield Manufacturing Co. manufactured multi-purpose sharpening machines during the 1913 to 1922 period. Research turned up nothing about the company other than frequent ads for the Hatfield grinding machine (1918), renamed the Hatfield complete sharpening machine (1920). The confusing similarity of the names is a coincidence; Andrew L. Hatfield was the inventor (US Patent 1,123,871) and the company was already established.
The ads were directed at retail hardware dealers, who, it was said, could quickly sharpen safety razor blades, shears, scissors, and household cutlery. An April 8, 1922 article in American Artisan and Hardware Record stated the machine had been made for 11 years and was available in 7 sizes. It was mounted on a cast iron frame resembling a sewing machine's, and powered by a small electric motor and round belt drive.
Internet searches did not find any surviving machines, but a few examples may have been preserved due to their compact size and novelty.
