Diablo has designed its new Steel Demon Recip Blades specifically to cut through thick metal. Each tooth is carbide tipped so the blades will last 20 times longer than a traditional bi-metal blade, according to the manufacturer. They’re treated with a non-stick coating to help reduce friction and the 1-inch body helps keep cuts straight. The blades are intended for cast iron, stainless steel, and high strength alloys from 3/16 to 1/2 inch thick. Available in 4-, 6-, and 9-inch lengths. Price: $8-15 / COO: Switzerland /freudtools.com
