This is a natural finishing whetstone believed to originate from Ozaki, known as Ozaki Suita. With an estimated grit equivalent of approximately #8000 and a hardness of Lv.4.0−, this is a high-quality Suita characterized by its moderately firm, dense, and tightly structured stone composition.

This particular stone is exceptionally substantial, weighing 2031g and featuring impressive thickness. Its generous size and weight provide excellent stability during sharpening, while its considerable thickness makes it particularly appealing for long-term use. The stone has a substantial presence that reflects the distinctive character of traditional Japanese natural whetstones.

The sharpening surface features a beautiful pale creamy-white to soft yellow background, decorated with intricate reddish-brown and ocher-colored veins. These delicate lines intersect across the surface, creating a striking web-like pattern reminiscent of a finely woven spider's web. The distinctive natural veining continues along the sides, further enhancing the stone's unique appearance.

The sharpening sensation is exceptionally smooth, offering the refined feedback characteristic of a dense, tightly structured Suita. The blade makes comfortable, consistent contact with the surface, providing a pleasant balance of smoothness and controlled abrasive resistance throughout the sharpening process.

A dark black slurry develops almost immediately upon sharpening, demonstrating excellent abrasive performance and efficient material removal. Unlike softer stones that produce thick, creamy, or sticky slurry, this stone generates a light, fluid, and free-flowing slurry that allows the blade to move smoothly and effortlessly across the surface.

Another outstanding characteristic is its excellent swarf-release performance. Metal particles and sharpening residue separate readily from the stone's surface rather than accumulating or clogging it. This allows the slurry to carry away metal particles efficiently, maintaining a clean sharpening surface and ensuring smooth, consistent sharpening performance.

With its balanced hardness, dense stone structure, rapid slurry development, and excellent swarf-release properties, this whetstone is well suited for finishing and refining kitchen knives, Japanese planes, chisels, and other edged tools.

Combining beautiful natural web-like patterns, the exceptionally smooth sharpening characteristics of a dense Suita, and an impressive weight of 2031g, this is a remarkable natural finishing whetstone. Its substantial size, excellent practical performance, and distinctive appearance make it an attractive choice for both serious sharpening enthusiasts and collectors of Japanese natural whetstones.
