In daily work environments, the PRO quality series of tools prove their worth over and over again, in particular due to their ergonomic handle shape in conjunction with hardened and tempered special steel. The seamless combination of hard and soft grip materials enhances force transmission, makes handling the tool more satisfactory and reduces strain.

The PRO grip system is based on three grip zones: the rounded triangular form of the upper grip zone enables force to be applied more effectively. The round cross-section in the central section combines firm grip with easier turning in the spin zone. The extended multifunction zone in the lower grip zone promotes faster tightening and loosening action. The three grip zones combine to form a sculpted longitudinal contour and to optimise contact pressure.

The comparison in the illustration shows that the handle sizes of the WITTE Pro series of screwdrivers are perfectly matched to the fastener sizes.
