It’s always fun to see tool designers incorporate design elements from other objects. You just know that someone at Fuller looked at a screwdriver, and thought, “this needs to be more like a revolver.” The result: the Switch-A-Bit 10-in-1 multi-driver.
As you might guess, the bits are stored in the handle. Pull the end cap to retract the bit and twist the revolver-like mechanism to select another bit. Then just push the handle forward to drive the bit into the collar.
It might not replace your favorite set of hand drivers, but it could serve well as part of an emergency tool kit in the car or home — any place where size is an issue. And its $15 price tag puts the Switch-A-Bit firmly in the “buy it if you feel like it” category.
