With cutting-edge technology and of quality and durability, Tramontina's professional knives are used beautifully well with any ingredient, cut, or recipe. The incredible high quality of the blades is a result of a thermal treatment which consists of hardening (heating the blade), sub-zero (cooling from 50 to -196 degrees), and tempering (increasing the steel elasticity) for a longer and more efficient life. The anatomical and ergonomic textured polypropylene handle, is directly injected on the steel bolster, ensuring a comfortable, safe use. The antimicrobial protection prevents and reduces the growth of bacteria and fungi. This technology is incorporated during the handle manufacturing process and lasts throughout the product's life, but should be cleaned thoroughly.Stainless steel blade DIN 1.4110.
