The Shinko sharpening stone is the second iteration of our combination stone line. For our more advanced customers, I think the Naniwa Chosera, Shapton Kuromaku and Suehiro stones are perfectly good but they don’t really offer any “great combination” stones.
Many customers who are new to the world of Japanese kitchen knives, probably spent a couple hundred dollars on a knife, is not ready to spend probably more than $100 for a sharpening stone. While our previous offering caters the budget side but lacks the performance compared to the professional grade Naniwa or Suehiro stones. This posts a slight problem: once a customer become more advanced and looking for new stones, this older double sided budget stone is no longer useful because the lack of performance.
This is the reason for creating the Shinko stone line. I contacted a trusted stone manufacturer in Japan and asked them to give me a couple combination stones that have similar performance to the professional stones and are wallet friendly. The result is a medium size 1000/5000 stone and a full size 1000/8000 stone.
These stones are ceramic stones that cuts very fast, harder compared to the Syousin stones and have great feedback. The 1000 grit is the same on both stones, the 5000 grit leaves a very nice haze finish on carbon steel, I love this stone for the excellent feedback and finish it gives.
