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

　　The Straight Grain Supply 220/400 Sharpening Stone was purpose-built to put a fine edge back on your bits and blades. 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 220 grit removes steel in a controlled manner for repairing small chips and minor blade damage, while the 400 side refines the blade for additional sharpening, or restoring a dull blade to a razor's edge.

　　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.
