The usual dimensions of an oilstone, excepting the slips (or small stones for sharpening gouges, bead irons, etc.) are: length, about 8 in.; width, 2 in.; and thickness, 1 in. A wide stone should never be selected owing to the difficulty of making it wear evenly, and to the care required to keep the plane irons sharpened on it to the shape necessary to produce the best results. The most convenient width is 1 1/2 in. A stone may be used by making the thickness side the working face; the tool should be moved across the stone from right to left and not always sharpened in the same place. A small oilstone about 4 in. by 1 1/4 in. is useful for sharpening spokeshaves, and pieces of stone or slips of various sizes and shapes are required for gouges, beads, etc. These often have to be rubbed to a particular shape (by one of the methods to be described) to sharpen a tool for some special purpose. A slip as shown by Fig. 437 is used for sharpening router cutters, etc. It will soon wear out of shape, especially the part A, but the shape may be restored by rubbing the stone on a piece of sharp gritstone, using silver sand and water, though a grindstone, if handy, will be preferable. It will be found better for some purposes to use the side of the grindstone, if it be in good condition, rather than the edge. Here also water and a little fine sand will be found an advantage. For sharpening bead irons and gouges this conveniently shaped slip can be purchased at most tool shops; its suitability is apparent. Sections of commonly used oilstone slips are shown by Figs. 438 to 442.
