▎ 摘　　要

NOVELTY - The blade (201) has a proximal end provided with an attachment socket (260a) mated with an oscillating drive element of a power tool and oscillate about an axis of oscillation. A distal end is provided with a distal edge formed into a cutting edge that includes a row of cutting teeth (215a) situated across the distal edge and a row of perforations a spaced distance at the row of cutting teeth. The row of perforations realizes a breakaway line and an additional cutting edge comprising an additional row of cutting teeth. The row of perforations is sized and shaped such that a portion of the distal end between the row of cutting teeth and the row of perforations nearest the distal edge breaks away from the blade revealing an additional cutting edge in responsive to a force applied orthogonally to a plane of the distal end of the blade. USE - Multi-edge oscillating saw blade for use in an oscillating tool for sawing, cutting, sanding, polishing, and grinding a workpiece e.g. metal, plastic, wood, or drywall (all claimed). ADVANTAGE - The blade provides multiple cutting edges that can be used sequentially as each cutting edge becomes worn-out or damaged is provided. A blade attachment can be removed from the tool and discarded, and replaced with a new blade attachment before work can continue such that replacement process results in wasted time as work can be stopped, the blade attachment removed from oscillating tools, and new-blade attachment procured, and secured to the tool. DETAILED DESCRIPTION - The blade is coated with ceramic, graphene, molybdenum disulfide coating, fluorinated ethylene propylene, polytetrafluoroethylene, fluoropolymer, or fluoropolymer with Xylan. The attachment socket is selected as a universal socket, a starlock socket, or a supercut socket. INDEPENDENT CLAIMS are included for: (1) a method for utilizing a multi-edge oscillating saw blade and (2) a kit. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a multi-edge oscillating saw blade with a breakaway cutting edge detached from a saw blade. 201Multi-edge oscillating saw blade 210a, 220a, 230aBreakaway cutting edges 215aRow of cutting teeth 245aRow of perforations 260aAttachment socket
