The greatest honor for a blacksmith is when his plane irons are used instead of disappearing into a collection. Therefore, the carpenter does not care whether the plane was lightly used or not. The only thing that matters is its quality, which is then reflected in the quality of the planed wood surface. Like all my Sadahide I planes, you can feel the master Korehide in this one, because it is perfect in every way. Likewise, the dai is made of selected beautiful red oak, as you can hardly find today. It is a pity that the master of this dai is unknown.
