The PB Swiss Tools screwdrivers with the Classic handle: Proven millions of times over decades, used everywhere in industry and assembly, for repairs, in craftsmanship, 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 cases. The pleasantly grippy surface and ergonomic grooves allow for high torque. The high-quality transparent CAB (cellulose acetate butyrate) 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 add a subtle vanilla scent to neutralize it.
