Whetstone holders are partially filled with water and hook conveniently on your belt. Scythe stones are used wet. This keeps the grain of the stone open, provides lubrication and makes a slurry of stone particles that will enhance the cutting action. Honing the edge is done frequently in the field. As soon as you feel a loss of efficiency in the cut, it's time to dress the blade. Available in sturdy plastic and galvanized steel. The plastic will hold two stones.
