Because of a specially developed handle shape, a new screwdriver marketed by B. Draper is said to be easier to use, cause less fatigue on continuous use and allow up to 50 per cent more torque to be applied to the screw than with conventional screwdrivers. A range of sizes from 4in. to 10in, in plain and cross-slot versions is available.
The design is the result of studies and tests carried out in Germany and the truncated cone shape of the handle is contoured to the skin pads and joints of the hand.
Screwdrivers incorporating the new handle are being marketed under the trade name Weralit Kraftform by B. Draper as sole UK concessionaire. The blades are of special alloy steel with a satin finish and an increase of 8 to 10 per cent in blade life is claimed over normal chromevanadium types.
