Our Pocket Keyhole saw is used to make curved cuts and closed inside cuts. Also great for making cutouts in drywall. Because it cuts on the pull stroke and has very sharp teeth, clean cuts are easily made in the most awkward of areas. The blade is made from SK-5 high carbon steel with well sharpened teeth. The chrome plated blade locks into one of two open positions for greater cutting efficiency. The ABS resin handle offers a comfortable, sure grip for extended use in difficult conditions. If the blade ever becomes damaged or becomes dull, it can be easily replaced. Blade thickness is 0.9mm with14 teeth per inch. Blade length is 5˝, and folded length is 6˝.
