ALTSTONE, founded in 2021
Positioned alongside Shapton and King as a first-tier Japanese whetstone brand
Very high ratings on Amazon Japan
Often includes a handwritten thank-you note from the developer—strong artisan vibe
Hard ceramic stone, slow wear
Excellent flatness retention—less frequent flattening
Precise angle control
Especially suitable for stainless steel & double-bevel knives
Not recommended for high-hardness Aogami single-bevel knives
(hard-on-hard, large contact areas may cause unevenness)
Don’t rush to rinse off slurry
→ Can help remove light rust on blade faces
For large chips:
→ Re-establish the edge with a steeper angle first, then blend the whole edge
After repairing single-bevel knives:
→ Always finish with ura-oshi / ura sharpening
High level of build quality, cutting power, and stability
A great entry into Japanese sintered ceramic stones without a high upfront cost

Rin: Clear, brighter, semi-mirror polish

Oiri’s personal favorite:
👉 Fukami #8000 (best slurry feel he’s used)

Flatten periodically for best performance
If you love ultra-smooth, buttery feedback, pair Rin with ALTSTONE Fukami
