ABSTRACT:
A pocket screwdriver has an oval body portion having a hole through the width of the body portion for holding a first double-ended screwdriver bit and a shaft portion having a hole for holding a second double-ended screwdriver bit. The bits can be interchanged by removing the bit from the shaft and using it to push out the bit from the body portion. The wide body portion enables the user to more easily use the screwdriver, while the hole in the body portion allows an additional screwdriver bit to be used.
