The Saw-Jaw is an improvement in woodworking tools, that makes changing your saw blades much easier. The unit easily connects using one hand when your saw blade is on the saw's arbor, and holds the blade securely while you tighten or loosen the arbor nut. This simple, yet innovative woodworking saw blade changer, easily wraps around your saw blade, protecting not only the blade during installation, removal and storage, but protecting your hands as well.
