If an iron box be used, Fig.

77, the oil is obtained simply by turning the stone over, for it rests on a pad of felt which is kept wet with kerosene.
Place the beveled edge flat on the stone, feeling to see if it does lie flat, then tip up the chisel and rub it at an angle slightly more obtuse than that which it was ground, Fig.78.The more nearly the chisel can be whetted at the angle at which it was ground the better.
In rubbing, use as much of the stone as possible, so as to wear it down evenly.

The motion may be back and forth or spiral, but in either case it should be steady and not rocking.

This whetting turns a light wire edge over on the flat side.

In order to remove this wire edge, the back of the chisel, that is, the straight, unbeveled side, is held perfectly flat on the whetstone and rubbed, then it is turned over and the bevel rubbed again on the stone.
