    • PROBLEM TO BE SOLVED: To provide a cutting tool having an excellent strength and rich in decoration property such that patterns appear to the edge of a blade. SOLUTION: A clad base material A of a prescribed thickness is formed by laminating stainless steel base materials 1 (1a, 1b...) alternately and rolling them by a hot rolling mill while heating them to make them metallurgically integrated. The clad base material A is forged to form a rugged part U on the surface, and then the whole clad base material A is heated to form a cutting tool substrate B. The rugged surface is ground to form a temporary blade part S' at one end edge part E. Then, etching treatment is performed to the whole surface of the cutting tool substrate B with an acid solution, so that a relatively base stainless steel part exposed on the surface is corroded to generate a hue difference by performing discoloration in each area defined by layer boundary lines L, create spot patterns and Damascus patterns on the surface, form a sharp blade part S by finish-grinding the temporary blade part S', and form the layer boundary lines L to the sharp blade part S.

    • PROBLEM TO BE SOLVED: To provide a user-friendly titanium clad steel cutter constituted of a titanium material, even if performing a quench hardening process for being used as a cutter steel, causing no delamination from clad joint parts and having superior lightweightness, corrosion resistance and durability; and to provide a method for manufacturing the same. SOLUTION: The titanium clad steel cutter includes: a stainless steel cutter steel material 1; a cutter outer skin material 5 composed of a titanium-based material; and a titanium clad cutter steel whose clad material is defined to be formed by superposing a plurality of materials, that are different from the stainless steel cutter steel material and the cutter outer skin material, between the stainless steel cutter steel material and the cutter outer skin material. In this titanium clad cutter, the plurality of materials, which are different from the stainless steel cutter steel material and the cutter outer skin material, are formed by sequentially superposing a third intermediate layer 2 of copper alloy, a second intermediate layer 3 of Mo and a first intermediate layer 4 of group V element metal, from the stainless steel cutter steel material side. The titanium clad steel is constituted, by a manufacturing method for performing vacuum deaeration in a previous step of a hot rolling process in particular, of the titanium material which causes no delamination from the clad joint parts and has the superior lightweightness, corrosion resistance and durability so as to provide a high-quality cutter material.

    • PROBLEM TO BE SOLVED: To provide an ideal composite metal material for eyeglasses, which is not too rigid, or too flexible to the external force of a bend and a torsion, and can achieve the ideal recovery elasticity and the form stability as a metal material for eyeglasses.
      SOLUTION: The present invention is a three layer cladded composite material C formed by metallurgically laminating cortex metal layers on both surfaces of a core metal layer. A material which hardens to the necessary hardness by heat treatment at a predetermined curing temperature is used as a metal constituting the core layer A, and a material which does not harden by heat treatment at the curing temperature is used as a metal constituting the cortical layer. By this arrangement, the core metal which has hardened by heat treatment and the cortex metal which has not hardened harmonize with each other complementarily, thereby presenting the recovery elasticity and the form stability suitable for an eyeglass frame G.
