Steel: Tamahagane (There is a "玉打/Tamauchi" mark on the neck of the blade, which means it is made of Tamahagane. But I'm sorry, I can't tell if it's true or not)

Additional Information: Used, a piece of the top of the blade fell off on one side, but it did not affect the use. It comes from a retired "Tateguya" in the Kanto region of Japan. This saw is one of the main saws he uses. 

The saw had been kept unused after being "metate".
