Oboro Knife #200, 4.4mm

By far one of the best lines of stones on the market, made by one gentleman who guarantees the quality and standard of everything produced. A word of caution, to those who are unfamiliar with these stones. These stones require advance techniques as well as other products to not only mantain the flatness but to also increse and revive its cutting power. One can not simply use an atoma plate to flatten this stone, that was a major mistake I made and it led to disastrous results, on both my expensive stone and on my atoma diamond plate When this stone is in its sweet spot it performs like magic. Skill is required to keep the stone flat as well as keeping the stone cutting aggressively. Overall this stone is a powerhouse and I will always have one in my collection. Its best quality is how even and precise it cuts and leaves scratch with no rouge deep gouges like other stones.
