Klein Tools' Flip-Blade Insulated Screwdriver is two drivers in one tool. The auto-eject mechanism works with just a twist, allowing you to flip the #2 Square- to the #1 Square-end of the blade simply and easily. A bright orange coating of insulation protects from electrical shock, as well as being flame and impact resistant. Klein insulated tools exceed the ASTM F1505 standards for insulated tools, and are clearly marked with the official 1000-Volt rating symbol.
