Sandrin Knives

Sandrin Knives and StaySharp™ Technology

Sandrin Knives brand founded by specialists in the production of tungsten carbide, the Italian company Turmond S.p.A. hit the knife market. The factory with over 40 years of experience, setting trends in the production of various types of carbide, used in many industries, this time tried its strength in the production of an innovative type of carbide intended for the production of knife blades (Polyhedral Tungsten Carbide – PTC). The project was a complete success and the knives of unprecedented hardness (71 HRC) with excellent sharpness (StaySharp ™ technology) lasting longer than in the case of other brands have become a permanent fixture on the market. The idea of carbide knives, its creator Alessandro Colombatto, summarized briefly as follows: “With an outstanding hardness of HRC 71, simply put, they’re nothing short of the hardest and most durable knife blades that have ever been made.”

Polyhedral Tungsten Carbide (PTC) with unexpected flexibility

Polyhedral Tungsten Carbide (PTC) was invented by Sandrin founder, Alessandro Colombatto and his team.

Polyhedral Tungsten Carbide (PTC) is composed of tungsten carbide and cobalt along with binder elements that have been used for decades in a variety of industrial applications, for example, crafting superior steel-cutting tools. However, traditional grades of tungsten carbide are brittle, so creating a durable knife blade from this material was previously thought to be impossible. Sandrin’s patented flexible PTC has solved this problem. In fact, our blades are so hard you can use the back edge of a Sandrin Knives to sharpen traditional steel knives.

Polyhedral Tungsten Carbide (PTC) in comparison to steel and ceramic

The physical properties of Polyhedral Tungsten Carbide (PTC) fall in between the properties of ceramic and steel.  Ceramic is harder than polyhedral tungsten carbide but very brittle. Steel is less hard than TC but has good bendable properties.  PTC is about 30% to 50% harder than steel with similar cutting properties as ceramic. A Sandrin blade has a weight of about twice that of a steel blade and a density similar to gold.

Hardness of PTC blades

The Sandrin knife has a hardness as measured in Rockwell at HRC71.  Most steel knives have a Rockwell hardness in the 50’s, while the hardest knives are in the 62 to 64 HRC range.  Mythical levels of knife level hardness have been reportedly achieved by one company at 67 HRC. Knives are truly in their own class in terms of a durable cutting edge.

New generation knives

As of today, the offer of the Italian manufacturer includes knives with a fixed blade, kitchen knives and knives with a folding blade (including Dellatorre, Lanzo, Torino, Monza knives)
