Cutlery description
Production area: Seki City, Gifu Prefecture (Seki Cutlery)
Classification: Small Knife
Blade elongated: 150mm
Steel: SK Material (Nippon Steel)
Pattern: Gold-mouthed black plywood together
(By sticking with the mouthpiece, dirt is difficult to accumulate at the boundary between the blade and the handle where dirt tends to accumulate, and can be used hygienically)

SK materials contain 0.55 to 1.5% carbon, and are special alloying elements such as chromium and molybdenum.
It is an unadded high carbon steel, and it is often used in tools.
The name Sk is an abbreviation that mixes English and Japanese. S is Steel, K is tool K.
SK materials, like S-C materials (carbon steel for mechanical structures), have an increase in carbon of up to about 0.6%.
Harder heat treatment hardness is easier to obtain, but if it becomes 0.6% or more, heat treatment hardness increases quickly
would be boring.
SK materials often require impact resistance and wear resistance rather than quenching, and among these, steel grades with a low carbon content
Striking applications, namely impact resistant orientations requiring toughness, high carbon content steel grades,
Because it is chosen for the direction of wear resistance you need, use it for the knife.
SK material has long been a common material for kitchen knives, and is the standard steel used for home use.
Since it is a corrosive material, it has a better sharpness than stencils such as molybdenum.
