A fret saw includes a cutting wire and fixed abrasive grains provided on the cutting wire by electroplating. Each of the fixed abrasive grains includes a core and a hard film coated on the core. The core is 1 to 60 micrometers in diameter. The core is made of a material selected from the group consisting of a Ti metal and a Ti alloy. The hard film is 1 to 40 micrometers thick. The hard film covers about 30% to 90% of the surface of the core.

Disclosed is a method for making absorbent for metal. In the method, at first, solution of first monomer and solution of second monomer are provided. Then, the solution of the second monomer is introduced into the solution of the first monomer. Finally, a microwave reaction is executed to provide micro-alls of absorbent for metal.
