The Tojiro collection is a combination of traditional Japanese techniques used hundreds of years ago; producing multi-layered razor sharp blades along with todays advanced technology. The Tojiro DP knives feature a full-tang 3-layered blade construction with a core of VG-10 super steel encased by two layers of highly rigid and rust resistant stainless steel. This formula of steel results in a 60° Rockwell Hardness, and provides a 9° to 12° blade angle for scalpel-like sharpness. The triple riveted traditional style Micarta handle with bolster contains heft and balance and the closed bolster collar allows for full and complete sharpening of the blade. Every knife is meticulously hand finished by artisan craftsmen. The Tojiro DP series offers a large selection of blade shapes and sizes to cover all your Asian & Western culinary tasks.
