    • A flexible base metal strip has a strong, tough and adherent abrasive armoring coating produced thereon in situ from abrasive particles of hard, high melting material selected from the group consisting of metal carbides, borides, nitrides, silicides and combinations thereof, and particles of a matrix metal, said matrix metal particles being in said armoring coating and fusion bonded to each other, to the base metal strip and to the abrasive particles to anchor and partially embed the abrasive particles therein with the particles projecting therefrom in the form of a series of sharp cutting edges. Attachment means are provided at each end of the coated strip for attachment of the strip to a suitable frame such as a standard hack saw frame. When properly secured and tensioned in such a frame, a small, flexible hand held abrading tool is formed which is suitable for hand working materials having a high hardness so as to be unsuitable to be worked by prior art abrading tools.

    • Method for the quantity production of armored saber saws from a long flexible strip of a base metal, consisting preferably of a heat treatable steel or alloy steel, which comprises: progressively punching out portions of said strip along one edge thereof at equispaced intervals to form the upper profiles of a series of saber saws comprising shank and blade portions of each, thereafter progressively coating the upper edges of said blade portions with a paste flux adhesive and with a powdered brazing metal, thence progressively applying to the so-coated strip edges, an overcoating of abrasive particles of a hard, highmelting diamond substitute material, thence progressively heating said strip at relatively low temperature to dry said paste flux and thence at temperature sufficiently high to austenitize said base metal and to fuse said matrix metal particles to one another and into a coating layer on said base metal, partially embedding said abrasive particles therein, thence progressively cooling said strip to temperature sufficiently low and with sufficient rapidity to transform said austenite to martensite and to solidify said matrix metal layer and permanently to bond the same to said base metal and to retain said abrasive particles permanently embedded in said matrix metal layer, thereafter progressively subjecting said strip to a tempering heat treatment, and thereafter punching out portions of said strip along the opposite edge thereof to form the lower profiles of said series of said saws and/or to sever said strip into finished saber saws.
