Oscillating multi-tools are ideal for making precise cuts in a finished wall. Dremel’s Drywall Jab Saw is the first accessory blade actually designed for that specific task. The sharpened tip of the blade allows for quick plunge cuts, and the thin profile makes cutting curves easy. The blade has small teeth that make a clean edge and don’t tear out the paper facing. The Jab Saw fits most oscillating tools with the use of the Dremel adapter (sold separately). Price: $10. 800-437-3635. dremel.com.
