Hone. A fine sort of whetstone, whereon to set a razor or penknife. It is of a yellowish colour; according to some accounts, it is holly-wood petrified, or changed into stone, by 1ying in the water for a certain time. Some in Arkansas are said to be thus petrified in a very short time. Several kinds of petrified wood are used as whetstones, but they are generally too hard and too coarse for fine edges.
