Nakayama (中山) (attributed) - Εργαλεία - (Toishi) φυσικός λίθος ακονίσματος

This is a compact natural sharpening stone, 天然砥石 (Tennen Toishi), likely from the famous Nakayama (中山) region, known for producing high-quality finishing stones for Japanese knives.

The stone features a fine-grained surface suitable for precision sharpening and finishing. Its small size makes it ideal for detailed work or as a portable sharpening tool. The surface shows natural coloration and patterns typical of authentic quarry stones, including brown layers and mineral inclusions.

Visible inscriptions and stamps indicate traditional Japanese origin and quality grading. As a natural stone, slight irregularities, color variations, and minor surface marks are expected and contribute to its authenticity.

This piece is suitable for collectors, craftsmen, or chefs who appreciate traditional Japanese sharpening tools.
