The little fish surrounded by a hook that was registered as the official emblem of rolled steel for fishhooks was also used for the handsaws, to communicate these special properties and quality of the blades.

In 1850, he founded the company that would become the largest sawmaker in the world: the Keystone Saw Works. Some five years later, Disston built a furnace—perhaps the first melting plant for steel in America—and began producing the first crucible saw steel ever made in the United States.
Materials for saw blades have varied over the ages. There were probably bronze saws in the time before steel making technology became extensively known and industrialized within the past thousand years or so.
