A solid steel Yanagiba knife by Hisamoto. I believe Hisamoto was a Tokyo-based manufacturer, and I recall reading that they originally branched off from Masamoto. The blade length is approximately 21cm, but this knife can cut through things that would require a 24cm blade on other knives. It's a surprising "Huh? It's short, but it can cut this far...?" moment. You'll be surprised if you're used to stainless steel. Despite its short length, it cuts relentlessly, so it was shorter than I expected, but it's fine. Since it's steel, this knife has rust marks, so please maintain it. The type of steel is unknown.
