What grit progression is used for hand sharpening, and what does each stage accomplish for the final

The progressive sharpening process typically follows a four to five stage grit sequence, with each stage serving a distinct purpose. The initial stage uses coarse stones around 300-400 grit to establish the primary bevel angle and remove any forge scale or irregularities from the edge zone. This stage shapes the fundamental edge geometry but leaves a rough surface with visible scratch marks. The second stage advances to medium grit around 800-1000, which refines the bevel surface, removes the coarse scratches from stage one, and begins to create a more consistent edge line. The third stage uses fine grit around 2000-3000, which polishes the bevel surface to reduce friction during cutting and produces an edge that can slice paper cleanly. Premium pieces continue to a fourth stage using very fine grit around 4000-6000, which achieves a near-mirror finish on the bevel and creates an edge capable of extremely clean cuts with minimal resistance. Some precision-sharpened pieces include a final stropping stage on leather to remove any remaining micro-burr and align the edge at the finest level. Each stage removes less material and takes more time than the previous one, which is why progressive hand sharpening is significantly more labor-intensive and costly than single-pass machine grinding.

How does the natural wood saya look and feel?

The 30.3-inch saya is made from natural hardwood with an unfinished surface that shows the pale wood grain. It has no lacquer or paint coating, giving it a clean, organic look. A brown sageo cord is tied at the mouth, matching the brown ito handle wrap.

What is the red saya made of and what texture does it have?

The 30.7-inch saya is made from hardwood wrapped in red PU leather with a raised crocodile-scale texture and sealed with a piano lacquer finish. It pairs with a black sageo cord and a real copper tsuba in gold-tone floral openwork, tying the red and gold color theme together.

How do 1095, T10, and Damascus steels compare in this collection?

These three steel types represent meaningfully different manufacturing approaches. 1095 high-carbon steel contains approximately 0.95% carbon, making it hard enough to hold a well-defined edge and capable of showing a vivid hamon when clay tempered. T10 tool steel adds a small amount of tungsten to the alloy, which improves wear resistance and produces a slightly finer grain structure - collectors often note that T10 blades exhibit a more refined, detailed hamon activity. Damascus steel (also called folded or pattern-welded steel) is produced by forge-welding multiple steel billets together and folding the composite repeatedly; when etched with acid, the alternating steel layers reveal flowing patterns across the surface. Damascus pieces are primarily chosen for their visual surface character rather than any single metallurgical advantage, making them a strong choice for collectors prioritizing decorative impact.

Is the tsuka handle wrap black, red, or both?

Updated Feb 2026

The tsuka uses a black-and-red cord wrap over red polyurethane leather samegawa, forming a diamond pattern with gold menuki accents set into the wrap. Handle length is 11 inches with a full tang core.
