The Mastersmith Cobalt 7.0 Set is Juntetsu's long-blade specialist kit — a matched pair of 7.0-inch ATS-314 cobalt shears built specifically for barbers and stylists whose work depends on the extended reach of a long blade. The set pairs a cutting shear with a texturising companion offering customisable 15-30% cut ratios, so a single kit covers everything from subtle blend passes to aggressive bulk removal. ATS-314 cobalt sits at 62-63 HRC — our highest hardness tier — which matters at 7.0 inches where every fraction of edge retention is carried across the longest stroke in the catalog. Hand-finished in our Tokyo workshop one at a time across 124 steps, the Mastersmith Set is the complete long-blade professional kit.
