How to Sharpen Watchmaker Screwdrivers
- 1). Fasten the screwdriver into the jig, a special holder that keeps the watchmaker's screwdriver stable. Jig models and styles differ, so fit your screwdriver in according to the manufacturer's directions.
- 2). Place the screwdriver and jig on a flat, level surface.
- 3). Check the screwdriver blade through a loupe. The loupe should attach to your eyeglass. The screwdriver's blade face needs to lay as flat as possible.
- 4). Put a drop or two of sewing machine oil on the oilstone. The oil helps the stone to cut properly, and it removes the ground-off metal from the screwdriver.
- 5). Place the screwdriver on top of the oilstone. Move the screwdriver back and forth across the oilstone two to three times. Turn the jig over frequently to sharpen both sides of the screwdriver blade. Continue sharpening both sides of the screwdriver's blade until it is the thickness you need.
- 6). Remove the screwdriver from the jig. Wipe the stone to remove the oil and pieces of metal.
