About as useful and handy as you can get, a screwdriver that doubles up as an easy depth gauge or ruler. The scale is laser etched onto the blade, it won't rub off over time and is clear and easy to read. These screwdrivers are Wiha's high quality with blades of high alloy chrome-vanadium-molybdenum steel and hard dull chrome plated against corrosion. The tips are precision ground, hardened and tempered, using the very latest technology. The SoftFinish handle is moulded directly onto the blade, and designed to transmit the maximum torque whilst remaining comfortable and less fatiguing. The sort of tool you'll never regret purchasing.
