GLASS HONES.
A glass hone is easily made, and no barber should be without one. Procure a piece of heavy plate glass and have a glass cutter cut it into pieces 3×8 inches in dimensions. Take the gloss off the face and also around the edges on a grindstone, and then finish by rubbing the face of the hone with pumice-stone kept wet with water. Continue this rubbing until the gloss is entirely removed and the hone is smooth. Before honing take a rubber, such as is used on a water hone, and, after wetting hone rub until you have a sort of lather. Hone on this as you would on any other hone. You will find it excellent for smoothing shears after grinding, or a razor after having been over honed.
