LamsonSharp Pro Walnut Kitchen Necessities stamped kitchen utensils and cutlery feature walnut wood handles with brass rivets that are unusually hard and durable. The natural color of the walnut wood may vary from tool to tool. The blades are either one-piece full tang or half-tang, made from hardened and tempered high-carbon stainless steel from Solingen, Germany. The handles are either double riveted or triple riveted with brass rivets. An Ulu knife was traditionally used by Inuit people (aka Eskimo) of Northern Canada and Alaska as an all purpose blade. In the modern kitchen, it can be used as you would a mezzaluna. Lamson & Goodnow, the makers of LamsonSharp knives, have been handcrafting cutlery since 1837 in Shelburne Falls, Massachusetts.
