🏠NSK Kogyo Diamond Sharpening Stone - Komon
https://komonjapan.com/collections/ns...

We recently had the opportunity to try out a 100,000 grit diamond sharpening stone from NSK Kogyo, a company I've always trusted for my sharpening needs. This ultra-fine grit stone was originally produced as a test product, and I was fortunate enough to be able to borrow it for a special trial.

In our previous video, we focused on sharpening with the Hakuto 400, 1500, and 12K grit stones, meticulously evaluating each one. Now, in this installment, we delve into the 30K, 60K, and 100K grit stones. This sharpening on this video was only for an edge check test, not such as the quality of sharpening Ivan does usually. So there may be some rough edges, but please let that go.


包丁研ぎ歴25年、現在は日本三代包丁産地である大阪府堺市で包丁会社に勤めているカナダ人です。

今回はNSK工業の試作品である、100,000番のダイヤモンド砥石を使った研ぎの第二部です。
前回の12万番の研ぎの続きです。30万番、60万番、100万番と研ぎ進め、それぞれ仕上がりの違いをテストしています。製品として完璧な研ぎというよりは、あくまでそれぞれの違いを見極めるための仕上げのため、多少粗い部分があるかもしれませんがご了承ください。

今回の試作品をお貸しいただきましたNSK工業様、いつも本当にありがとうございます。
