The 2019 Red Dot Award winning Thomas Keller Signature Collection by Cangshan is a model of precision and craftsmanship. Slim, sleek and exceptionally well balanced these knives have been meticulously designed with Michelin starred chef Thomas Keller to ensure each knife performs perfectly in their distinct function. Sharp, bold angles create a keen focus on the stunning silhouette and minimalism of the knife. Each knife is forged from Swedish Damasteel® RWL34 Powdered Steel, an extraordinarily fine grained, high alloy steel known for its excellent edge strength, hardness and corrosion resistance. After an ultra precise 6 stage heat treatment these knives have a Rockwell Hardness Rating of 61 +/- 2 which means they can take an incredibly sharp edge. The internal structure of the steel gives the knives remarkable edge retention without the brittleness commonly associated with harder steels. The knives will be featured in his critically acclaimed restaurant The Surf Club Restaurant located in Surfside, Florida, and the newly opened TAK Room in New York City’s Hudson Yards.

Powdered metallurgy had a long and fascinating history before gaining large scale acceptance in the 1900s when it became a viable means to produce tungsten filaments for light bulbs. The process allows for the creation of alloys that are impossible to create through traditional forging. Powdered metals are thoroughly blended allowing for finely tuned control of the density and properties of the subsequent alloy. The powdered metal mixture is then compressed and sintered in a controlled atmosphere. Sintering is the process where high heat is applied to the solid materials causing them to bond and form an alloy without ever becoming molten. This allows metals with high melting points to be uniformly bonded together creating alloy steels designed to exact specifications. Damasteel® RWL34 Powdered Steel offers high edge strength, durability and high corrosion resistance.
