Fig. 25.—The Beveling or Angle Blow.
When the metal is to be drawn tapering on two opposite sides, it should be held to the proper angle on the anvil to establish the taper desired on the bottom, while the hammer blows are delivered so as to form a similar taper on the upper side. (See [Fig. 25].)

A, correct position; B, incorrect position.
Fig. 27.—The Leverage Blow.
Blows of this kind are used for chamfering corners or edges, and may be delivered at any required angle. They are also used when drawing metal to a point, either square, round, hexagonal, or octagonal, but the metal should be held on the anvil, as shown at A, [Fig. 26]. Then the hammer will not come in contact with the face of the anvil, as shown at B. If the hammer strikes the anvil, small chips of steel are liable to break off from the hammer at the place indicated by c, and cause serious injury.
