The Kasumi Tora Yanagi knife 27cm is a single bevel slicing knife with a long narrow blade that smoothly slices through raw fish and preserves the integrity of each ingredient's freshness. 
When preparing sashimi and nigiri sushi, the goal is usually to have cut surfaces that are smooth, shiny and even, in order to maximize the taste. The construction of the yanagiba is designed for this purpose.

Length: The long blade allows the user to cut a block of flesh in a single stroke. This prevents zigzag cutting, which creates a serrated cross section.

Thinness: The blade is very thin behind the edge which allows the cut to be made using primarily the weight of the knife. Greater force or thickness would result in tearing or bruising of the flesh.

Nonstick properties: The back face (urasuki) is concave to easily detach the blade from the substance being cut, and the front bevel (shinogi) allows sliced piece to be easily removed from the blade after cutting.

For right-hand use, the yanagiba has a bevel on the right side and a concave on the left. This allows a more acute angle compared to most double bevel knives and nonstick properties.

The blade of this model is made of stainless steel (AUS8) with a high content of molybdenum and vanadium, so that the knife does not absorb odors and does not transfer tastes from one product to another. 

On the surface of the blade a solid oxide film is formed, which provides additional protection against corrosion.

The knife is equipped with a black cylindrical manoglia wooden handle of Japanese type, equipped with an O-ring for better stabilisation.

Kasumi knives are produced by Sumikama Hamono Cutlery in Seki, Japan.
Sumikama Cutlery specializes in producing knives from very advanced materials with the most advanced manufacturing techniques. 
Kasumi TORA knives are made of AUS8, a high carbon, low chromium stainless steel that has proven, over time, to be a very good compromise between toughness, strength, edge holding and resistance to corrosion.

The edge on a Kasumi knife is beveled at a 26° angle creating a very sharp edge.
