The PB Swiss Tools screwdrivers with the Classic handle: Proven millions of times over decades, used everywhere in industry and assembly, for repairs, in crafts, and in home and leisure activities. The round basic shape is ideal for quick turning and versatile work. The slim handle saves space in tool bags and boxes. The pleasantly grippy surface and ergonomic grooves allow for high torque. The high-quality transparent CAB (Cellulose Acetobutyrate) material is extremely impact-resistant, resistant to oil and gasoline, and also recyclable. Since the modified natural material can develop an unpleasant odor in airtight boxes and drawers, we mix in a subtle vanilla scent for neutralization.
