Abstract
In this article, the following points were shown about the historical change from the single iron plane to the double iron plane based on literature, archival photographs and actual samples.
1 In the early Meiji period when the western plane was imported, the construction and working of the double iron plane based on the westernplane had been elucidated.
2 The double iron plane already existed in the middle Meiji period as a plane for handicraft.
3 The double iron plane seems not to have used by artisans (carpenters) in the Meiji period, but it was used in the early Showa period.
4 The cap iron of a double iron plane with a hole in a fixed position is a recycled tobacco mincing blade.
