The position of the hands is the one with the palm that supports and pushes

Chordal Stroke

DESCRIPTION The past is the chordal excavation technique more aggressive and effective towards our mirror. In fact it allows to remove a large amount of material in a shorter time compared to the other past. On the other hand is a technique that does not allow to obtain a regular shape, It should therefore be used only in the initial stages of blanking and up
