Shikkoku Katana Sword (漆黒) – Jet Black

Shikkoku (漆黒): absolute black

In Japanese, shikkoku describes an intense, consuming black, the black of polished urushi lacquer, deep and entirely without colour. It is jet black in its purest form: a tone long associated with quiet restraint and inner strength.

This katana takes that idea to its natural conclusion. From blade to scabbard, everything is black. The result is an austere, commanding presence, the mark of a warrior who favours shadow over display.

A black blade in manganese steel

The blade is forged from manganese steel, a robust alloy appreciated for its strong resistance to impact. Its defining feature is the black finish that covers the entire surface, uniting it with the rest of the fittings in a single, cohesive tone.

There is no hamon, no bo-hi: the plain black surface allows the curvature and silhouette of the katana to speak on their own terms, without ornament.

A restrained, all-black mounting

The round tsuba is worked from a black alloy, its pierced openings lightening the form without breaking its severity. The fuchi and kashira, in plain black alloy, remain deliberately understated, a seamless continuation of the guard.

The tsuka combines a wooden core with a faux black ray-skin wrap, bound in a diamond-pattern beige tsuka-ito: the only light note in the mounting, which sets off the black menuki beneath. The habaki, in gilded brass, is pierced and reveals a black alloy surface textured with fine raised dots (nanako), the single golden accent of the entire piece.

A saya painted in granular black

The saya is crafted from solid wood, painted in a granular black that gives a matte, tactile finish and a confident grip. The koiguchi and kojiri are black, maintaining the continuity of the scabbard. A beige sageo, matched to the tsuka braiding, provides the only counterpoint.

Dimensions and handling

With a blade of 71 cm and an overall length of 103 cm, Shikkoku carries the proportions of a traditional katana. Its 26.5 cm tsuka allows a firm two-handed grip, while a weight of 1.3 kg strikes a considered balance between presence and manoeuvrability. At 105 cm in its saya, it displays with equal ease on a wall mount or a table stand.
