The Drill
Drilling is a delicate operation because it requires both precision and strength. The drill is an ancient tool, anterior and Neolithic. Guided by the chuck, the drill bit can intervene to an exact point, in variable diameters, on soft metals.
The wooden handle is grasped in hand, the wood slipping between the index and the middle finger. The flywheel is launched by rotating the shaft, between the index finger and the thumb.
By pressing gently and slowly at first on the handle, one accelerates a movement back and forth by winding and unfolding the leather thongs passed through a hole at the top of the wood. By pressing harder, you quicken the pace.
The tool is unusual in that it reduces the hand to the function of a driving force as with the first machine tools, but retaining its essential role as a skilled guide.
