A quality butcher's knife for everyday use with a high carbon stainless steel blade and a hygienic, boil-able sanitary handle. Mundial is a well-known brand of knives manufactured in Brazil? The company was established in Brazil before WWII by a German knife manufacturer. The production still bears the hallmark of its origins. Knife handles are polypropylene, which can be boiled, and the blades are of high-carbon stainless steel, which is easy to sharpen whilst being resistant to rust (not rustproof). These are mid-range knives.
