Chosera Stones

What are 1×4 KME Chosera Water Stones used for?
These stones are designed for use with the KME guided sharpening system. They’re premium Japanese water stones that offer excellent cutting speed, smooth feel, and great feedback, making them ideal for sharpening knives to a high level of sharpness and polish.

Do KME Chosera Stones need to be soaked before use?
Yes, they are soak-type stones. A quick 5–10 minute soak before sharpening helps saturate the surface for smoother cutting and reduces the chance of glazing. After soaking, splash on water as needed during use.

What grits are available for 1×4 KME Chosera Stones?
The KME Chosera lineup typically includes grits like 400, 600, 800, 1000, 3000, 5000 and even 10,000, covering everything from setting bevels to high-level polishing. You can build a full progression for excellent edge refinement.

What are 1×6 Naniwa Chosera Water Stones used for?
The 1×6 Naniwa Chosera Stones are the same high-quality water stones as the KME version, but in a larger size suited for use with sharpening systems like Jende JIGS, Edge Pro, or freehand sharpening. They’re known for their fast cutting, superb feedback, and fine polish.

What’s the difference between 1×4 and 1×6 Chosera stones?
The only major difference is size. The 1×4 version fits compact guided systems like KME, while the 1×6 version is better suited for larger systems or more freehand control. The stone material and performance are otherwise the same—both deliver excellent results.

Are the 1×6 Chosera Stones splash-and-go or soak-only?
They are best treated as soak-type stones. A short soak of 5–10 minutes helps activate the binder and prepare the stone surface. Avoid over-soaking, as it may weaken the bonding agent over time.
