When moving the chisel forward, never apply a greater force than your controlled arm weight. It is dangerous to use your body weight since your anchor will be unable to withstand such force. If greater pressure is required, a mallet should be used.
The tapping technique combines the fist and anchoring positions. Grip the chisel in the fist position, making sure your forearm is correctly anchored, and gently tap the handle of the chisels with a mallet.
The chisel will be pushed forward by the tap, making a cut, but the anchor will immediately force it to return to its original position. This provides a controlled burst of power and when the cut needs to be advanced, the anchor can be relocated.
