Skew Products SP-1001 SkewDriver Bevel-Gear Offset Screwdriver. Turns manually with the handle or remove it for use with power screwdrivers. The SkewDriver is the original bevel-gear drive tool, based on a patented offset screwdriver design. Using the rotary action of a straight screwdriver through precision hardened bevel gears, the SkewDriver gets into those hard-to-reach places where regular drivers can't fit. It replaces ordinary finger-ratchets, stubby screwdrivers, and awkward S-bend offsets to speed work time and improve efficiency, solving those impossible access problems.
It gets at screws impossible to reach with inline screwdrivers. Operation with the manual handle or with a cordless drill is easy and fast. My freinds used mine and are now ordering their own.
