India Abrasive File · Aluminum Oxide · Produces Long Lasting Edges Falcon Tool India Abrasive Files are made of aluminum oxide abrasive which is the preferred abrasive for producing exceptionally sharp, long lasting edges and for high quality steel work. They are brown in color and filled with oil during the manufacturing process. India Abrasive Files are available in coarse, medium and fine grits. Coarse (C) 100 Grit Medium (M) 240 Grit Fine (F) 320 Grit India Bench Stones produce a strong, keen, long-lasting edge on all types of knives, plane blades, chisels, and more. They are ideal for hand dimensioning and sharpening of tools that need a flat, sharp edge. The coarse grit stone quickly restores worn edges. The medium grit produces the average edge needed for most tools. The fine grit produces an even sharper edge. Available in sizes ranging from 1" x 1/4" x 4" to 2" x 1" x 8". Although oil-filled, we recommend using an oil such as our Stoning Oil or Polishing Lubricant and Diamond Thinner for best results as the use of oil increases the sharpening action and minimizes the clogging of the stones' surface.
