Stanley Compass Saw: 12 in Blade L, Steel, 18 in Overall L, 11, Multi-Component

The sharp tip of jab saws plunge cuts into materials so the serrated blade edge can saw through them. Also known as keyhole saws, they are commonly used to create electrical box cutouts in drywall and to cut free-form holes in a variety of building materials. Their long, narrow blade mounts to a straight handle and cuts on both the push and the pull stroke. They are typically used with one hand.
