Mayhew Tools celebrating 150 years of quality manufacturing! In 1856, starting as a small tool house in the town of Shelburne Falls, MA, the founders of Mayhew Tools dedicated themselves to the highest standards in American manufacturing of punches and chisels. With the Dominator and Cats Paw series being two of there most popular. The company has grown to encompass a much broader product line, but the basic commitments to quality and standards have remained solid and unchanged.
