How to re-sharpen?
Sharpening the cutting edge
①Hold the bit as shown at approximately a 45-degree angle. Place the file at a near-horizontal position, making sure it is flush with the cutting edge.
②Touch the left edge of the file to the bit's spine, which will be used as a guide. File forward repeatedly only. Do not file in reverse.
Sharpening the spur
① If the spur has any burrs, lightly file them to create a clean edge.
②Hold the bit so the side of the spur is facing up. Place the file flush with the spur. File with a smooth forward motion.
