This extra coarse (70 grit) Abrasive Sharpening Hone is designed for heavy-duty sharpening of damaged and abused power and hand tools around the shop, farm, home and garden. It makes simple restoration and sharpening easy for everyone.

To use the Heavy Duty Sharpener, begin by carefully holding the sharpener with one hand. Since this sharpener does not have a handle, you will have to be very careful not to cut yourself.

Hold the tool that you will be sharpening firmly with the other hand. If you are sharpening a machete, it is good to either clamp the machete to a workbench, or rest the machete along its length, holding the handle for stability. You want to make sure that the blade is supported and does not flex.

Begin sharpening by taking the sharpener, and matching the angle of the sharpener to the edge angle of the tool. Start by pushing the sharpener across the edge of the tool while maintaining a consistent angle and using as much of the sharpener as you can for each stroke. You want to be moving across the blade and using the length of the sharpener simultaneously.

Use moderate pressure. Sharpen one side, then the other, until you see that the edge has become very sharp. Do not worry about the way that the edge looks, since it might look a little rough. The tools you are sharpening are meant for heavy use, and as long as they are sharp, they will work well.

During this process, be extra careful not to slide your fingers across the blade, since it will be very sharp.

Be Smart, Be Safe and Stay an Edge Above the Rest!

CAUTION: Knife sharpening is an inherently dangerous activity. Used properly this sharpener cannot hurt you but a carelessly handled blade or pointed object can.
