All Purpose Sharpening & Finishing Stone · Produces Sharp Edges · Precise, Polished Finishes Falcon Tool's Arkansas Files are classic, natural sharpening and finishing stones. They are made of novaculite and are very dense, fine-grained natural stones that are ideal for creating the sharpest edges and the most precise, polished finishes. They are the ultimate finishing stone! Our Hard Arkansas Pen Knife Piece measures 4" x 1" x 1/4". Arkansas Stones should be used with 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.
