The Japanese Temagari is the traditional equivalent of a small chainsaw, designed for felling small trees and cutting them up. The pitch, tooth geometry and ergonomics have all been developed to excel at one task - crosscutting green wood.
The teeth are very aggressive - 4.5 - 5.5 tpi progressive pitch, very little rake (I'm guessing 5 degrees) quite a lot of slope and absolutely masses of fleam. The toothed edge is 360mm, about 14", the whole saw is just under two feet. The blade is taper ground, both from teeth to spine and handle to tip, but well tensioned so it has a nice stiff springiness.
This is a really nice saw, please don't forget to oil the blade before you put it away.
