Our 7˝ Artisan Santoku Knife is designed for the professional chef. The blade is similar to a Western Chef knife with the cutting qualities of the best Japanese made knives. The maker adopted powdered steel technology so that the blade would have a high hardness (Rc64) and would resist rust. The blade is a forged triple layered structure. The center layer is SRS-15 powdered steel originally designed for metal cutting tools The cladding layers are soft SUS-405 stainless steel. This gives the blade an exceedingly tough, long lasting and chip resist edge but yet is easy to resharpen. A forge welded bolster seals the blade from the handle. And for strength and longevity, the triple riveted tang runs the full length of the handle. The well shaped, comfortable handle is made from multiple wood layers infused with resin for a life time of use. Both handle and tang are tapered for better balance and reduced fatigue during long use. The blade length is 7˝, and overall length is 12˝.
