The Tramontina Professional Series 7" blade Santoku Knife is made of stainless steel and has a black nylon handle. Made in Brazil by a European immigrant, the blade is expertly sharpened and honed to a keen, long lasting edge for maximum cutting performance. The blade is satin finished and made with stain-free, high carbon chrome molybdenum stainless steel. Properly beveled and fully tapered to maintain its edge. Ergonomic shaped, water resistant, nylon handle provides balance and comfort when gripping. The handle is injection molded directly onto the tang and around the solid stainless rivets to discourage bacteria or residue from accumulating. The Tramontina Professional Series is Tramontina's top line of professional cutlery. The knives have been designed around the traditional style preferred among demanding chefs while ensuring comfort, ease, and maximum performance. All of the Tramontina Professional Series Cutlery blades have a satin finish and are constructed of stain-free, high-carbon chrome molybdenum steel that have been hot-dropped forged. The ideal metals have been selected for each of the knife's main components - blade, bolster, and tang. Using micro-welding technology, the components are solidly and reliably joined to provide maximum durability and performance even when used under the most extreme conditions. The Tramontina advanced ice-hardening process provides sharpening durability and cutting edge performance. Each Tramontina knife is expertly sharpened by skilled workers. I have only had to keep mine touched up with a butcher's steel to maintain the razor like edge.
