For use on all edged tools and portable for field use; American made

　　The Straight Grain Supply 80/220 Sharpening Stone was purpose-built to bring well worn bits and blades back to life. Each stone is made from evenly-graded Aluminum Oxide granules, which allows the stone to cut faster and does not require oil to be added to the sharpening process.

　　The 80 grit removes steel in a controlled manner for repairing chips and re-shaping blades from heavy use, while the 220 side refines the blade for additional sharpening, or keeping the edge maintained. It’s the perfect combination for repairing your blade by hand, without having to worry about damaging the steel’s temper on a bench grinder or other automatic sharpening device.

　　Included with each sharpening stone is an American-made EDPM rubber band, which provides additional grip when manipulating the stone. The band is removable and can be used for a variety of outdoor or everyday carry applications. While gloves are highly recommended, the recessed finger grooves and band combination will keep your hand positioned well above the cutting plane for a secure grip throughout the sharpening process.

　　Please Note: Each stone is set and cut by hand. Some variation in size and color may occur. This is a result of the manufacturing process and will not affect the performance of the stone.
