Doug MacKenzie makes a range of replacement and custom handles of axes, adze, sledge, hammers, picks and wheel barrows. Most get sold for retail but they can always find you a new handle and fit it to your tool. There is no need to throw an axe away because the handle comes loose. Doug makes custom screen doors and also has a number of designs you can chose from. They also make charcuterie paddles, spindles for stairs and other custom orders.
