The Senzo Professional series uses carefully selected steel materials to maximize the sharpness and wear resistance of the blades. The blades of the Senzo Professional Series use SG2 powder steel, which can acquire the highest class of hardness as a stainless blade steel. SG2 powder steel is used as the core material of the cladding material consisting of three layers, and rust-resistant stainless steel is used on both sides. Therefore, a beautiful ripple like a Japan sword emerges on the cutting edge. The handle material is laminated reinforced wood. It is a material that has increased durability by impregnating natural wood with resin and features a mosaic pin.
