240mm High Carbon Gyuto

#85

Lightweight and fairly large Gyuto in high carbon steel. Thinly ground edge for a great cutting performance.

The steel is 1095 high carbon steel, hardened with clay on the spine to create the hamon. It was 66HRC after quench and has been tempered back to 63HRC, measured near the edge. The upper part of the knife is very soft with a hardness around 40HRC.

Weight: 186g

Length overall: 365mm

Balance point: Under the T of the logo.

Blade

The blade has a mostly flat grind, but transitions in to convex at the higher part of the blade. It is tapered from the bolster to the tip.

The spine and choil has been rounded to make the knife comfortable to use with a pinch grip.

This blade is quite thin behind the edge, 0.1 to 0.15mm just over the secondary bevel. The thickness 10mm from the edge is around 0.9mm.

The blade has been differentially hardened, using a clay cover on the spine. This make the blade “soft” and flexible at the spine, while leaving the edge fully hardened.

 

Steel: 1095 high carbon steel

1095 has been a very popular high-carbon steel for knives for many years. It holds a great edge and is very easy to sharpen, but rusts easily if not cared for.

 

Heat treatment: The blade has been differentially heat treated inhouse in a PID controlled furnace at 815°C and quenched in fast specialty quenching oil. Finally it is tempered in a PID controlled oven to the final hardness.

The differential hardening of the blade is produced by covering part of the blade in clay during heat treat and results in a soft spine but a hard edge. What is called a hamon in Japanese sword making.

 

Hardness: 63 HRC

Height at heel: 51mm

Thickness at

  • Spine at bolster: 2.1mm

  • Spine halfway: 2.0mm

  • 1 cm from the tip: 0.5mm

Handle

Material: Ebonite (Ponceau color)
Ebonite is an interesting handle material made from natural rubber and linseed oil. It is very hard and takes a very high polish, but it still pleasant to the hand.

Bolster and spacers: Black Ebonite bolster, G10 and stainless spacers.
