Height: 18.7mm
Weight: 583g
Grit Range: 6000-8000

1-5 Scale: 1 = Less, 5 = More

Recommended Usage: Fast, bright Kasumi or polished Hagane (Ha-to?); scratch removal from sub 6000 grit; final pre polisher; push cut tools; Uraoshi sharpening; microbevels.

Notes: Amazing value, super consistent specimen. Provides a very fast and easy bright Kasumi. A little harder than more expensive Uchigumori, so be mindful with pressure. Hard enough for push cut tools. The line can only be felt with the fingers when actively feeling for it and not when polishing wide bevels, and it has no effect on the result. A really awesome option for those who want to try their first Uchigumori.

Notes: An extremely rare vintage Hideriyama Suita, especially in this large format. A true pleasure to use — it offers silky feedback with a slurry that develops quickly and yields an exceptionally consistent scratch pattern. The resulting kasumi finish is warm and rich and can be achieved with ease and speed. Depending on your approach, you can stop early for a hazy-to-frosty kasumi, or continue on in your polishing sequence for a brighter finish.

Thanks to its generous surface area and substantial thickness, this stone will provide years of use. However, as it’s not particularly hard (though not overly soft either), it’s important to work the surface evenly to avoid localized dishing. It’s likely too soft for push-cut tools, but perfect for wide bevel polishing, even convex grinds.

This is an outstanding stone for collectors due to its rarity, quality, and vintage provenance. While best suited for intermediate to advanced users, its forgiving nature also makes it accessible to mindful beginners.

Recommended Usage: Hazy to frost kasumi, pre or pre pre polisher, convex grinds, refined but textured edges.

The Tempered Glass Lapping Plate is designed for efficiently and thoroughly flattening NSK Kogyo Diamond Stones, especially for grits 1500 and below. Its large, extremely hard, and perfectly flat surface allows for more consistent flattening than using only the Stone Resurfacer or NSK Kogyo Flattening Stone, while also helping to reduce wear on flattening stones over time.

Because tempered glass maintains flatness exceptionally well, it provides a long-lasting, reliable reference surface for your stones. For best results, it should be used in conjunction with the other flattening tools.

Recommended Flattening Sequence
 1. Stone Resurfacer
 2. Tempered Glass Plate (with slurry generated from the resurfacer)
 3. NSK Kogyo Flattening Stone (closest respective grit)

This sequence ensures a fully flat surface and prolongs the life of your stones and flatteners.
