ABSTRACT:
This invention consists of three new features which on their own or in combination, improve the usefulness of the existing drywall jab saw. The three new features are the addition of fine teeth to the top of the blade, a blade with equally spaced holes along its length which are used as a rip guide, and a notch at the end of the handle to help remove narrow rips of drywall.
