Got a question about it in novel Itai no Wa
Japanese Chopping Hatchet
With its leather covered storage case (which has a belt loop) and its laminated steel blade construction, this is a traditional gardening tool that’s terrific for cutting small branches. The thick back of the blade makes it unusually (and intentionally) heavy for its 6-1/2″ length, and this translates into great cutting momentum when you are working. It chops like a dream.
