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 1K Traditional is the workhorse of the line - the grit where most sharpening sessions begin and where the bulk of metal removal happens. It is a well-balanced medium stone: cuts actively enough to work efficiently, leaves a scratch pattern clean enough to progress directly to a 4K or 6K without an intermediate stop. At 20mm thickness it provides years of use under regular sharpening. Soak 5-10 minutes before each session. The name changed from Traditional 1,000 to Standard 1,000 - same stone. Flatten regularly with a diamond plate. 210mm x 70mm x 20mm.
What Customers Are Saying: Two reviewers confirm solid performance. One lapped it immediately after a 30-minute soak and found it flattened quickly and evenly - a good sign for long-term consistency. Described as a reliable, straightforward stone that does what a 1K should.
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.

After a 30-minute soak I drew a grid and lapped it on a DMT-8C (325 grit) in my kitchen sink, under dripping water -- it didn't take long to finish, and a second "verification" lapping took even less time.
Cut to almost two months later, where I again soaked it for half-an-hour, lapped it, and then set to work resetting the bevel on a 5/8", quarter-hollow Little Valley straight razor. It's a fast cutter, and the work went quickly (at least, quicker than I'd expected).
Boy, is this a thirsty stone! Initially, I worked with the stone in a holder, on my kitchen counter. But I couldn't make more than a dozen back-and-forth passes before it was dry and needed spraying. After about ten minutes of this I decided to move my setup into the sink, and continued under dripping water. BIG difference! Next time, I'll let it soak for an hour, but bypass the counter and work in the sink.
I'm glad I bought this stone, and feel no need, whatsoever, to seek anything else for my bevel (re)setting chores.

CON: It should be a full 3" wide -- the 70mm (2.76") is far less than the "normal" 3", and forces me to work with "X" strokes, which I hate, rather than my preferred up-and-back motion. It might not be a problem for others, but it's definitely a functional criticism (rather than a cosmetic one).
