| This is another example of a broad ax. It is also a knife-edged broad ax, meaning that its blade edge is beveled on both sides. The knife-edged broad ax usually was given a straight handle.
This ax is stamped on one face with the name "Underhill", which refers to the Underhill Edge Tool Company. The Amoskeag Ax Company, of Nashua, New Hampshire, produced axes in the mid-1800s. In the year 1879 the Underhill Edge Tool Company bought out Amoskeag. Underhill became part of the American Axe & Tool Company, of Glassport, Pennsylvania in 1890.
