The Wiha Insulated SoftFinish SlimLine Blade Holder is the standard for premium quality featuring an ergonomic cushion grip handle for comfort and control, dual durometer construction for long-lasting durability, handle directly molded to the blade holder for a permanent bond, and parallel flats to prevent table-top roll-off. The Wiha Insulated SoftFinish SlimLine Blade Holder consists of Wiha engineered premium quality tool steel for strength and durability. Every single Wiha insulated tool is individually tested to 10,000 volts AC and rated to 1,000 volts AC (1,500 volts DC) for safety and peace of mind in energized applications. This tool is VDE Certified and meets EN/IEC 60900 testing standards for protection against arc flash explosion, ASTM F1505 standard specifications for insulated and insulating hand tools and CSA testing benchmarks for safety and performance. Wiha SlimLine Blades have 33% narrower blade shafts compared to Wiha insulated screwdrivers and allow access in hard to reach deep set fasteners in control panels, terminals, and other areas that standard insulated screwdrivers cannot access because of their added insulation. Wiha SlimLine Blades replace a set of insulated screwdrivers with a compact set of blades when paired with a blade holder and screwdriver handle. The SlimLine Blades work specifically with Wiha SlimLine blade holders and drivers. SlimLine Blades can be paired with different combinations of handles to work in your application.
