Naniwa has been producing sharpening stones in Osaka, Japan for decades and is one of the most widely trusted stone makers in the world. The Traditional line - also sold under the Standard name after a recent rebrand - is the entry point of the Naniwa range: thick 210mm x 70mm x 20mm stones at a practical price, built to last years with regular use. These are soaking stones. Submerge them for 5-10 minutes before each session; coarser grits absorb water faster than fine ones. Keep water on the surface during sharpening, and flatten regularly with a diamond plate to prevent dishing. CKTG imports these directly from Naniwa Abrasives in Osaka.
The 6K Traditional sits at the upper end of the Traditional range and produces a polished, refined edge suited for fine kitchen work. After a 1K or 4K session this stone removes the coarser scratch pattern and leaves an edge with a light mirror quality that performs well on fish, soft proteins, and precise vegetable work. It is also a useful bridge stone if you are progressing toward an 8K or 10K - it closes the grit gap enough that the finishing stone can work efficiently without having to remove excessive material. Soak 5-10 minutes before use. The name changed from Traditional 6,000 to Standard 6,000 - same stone. 210mm x 70mm x 20mm.
Care Instructions: Soak for 5-10 minutes before use. Add water as needed during sharpening. Flatten with a diamond plate when the stone develops a dish. Store dry between sessions.
