The first double bit axe is believed to have been produced in the 1850's in the PA region. Typically, one blade was sharpened to a finely honed, narrow felling edge, while the second blade was ground slightly blunter and used for knots, cutting near the ground, or in other instances where a finely sharpened blade was more likely to be damaged. ⚒ New items posted this week!
