    Abstract

    The Six Bit WristDriver was created for the person who wants a more efficient tool not available anywhere else. The Six Bit WristDriver makes your work easier, faster, it's a pleasure to use. It's a new type of screwdriver, one with 6 different bits, easy and fast to change. The short shaft is on purpose, extensions can be added. Replacing bits are a snap, pull the old bit out of the shaft, select one of the five bits (your choice) on the handle, press down on the end of the one you want, the opposite end pops up. Pull it off and replace with the one you were using. Place the WristDriver in your hand and rotate the wrist only (not forearm) notice how the bit centers in the screw slot. The “S” angle can be used to tighten or loosen the fastener. The blade is electrically isolated from the bits on the handle.
