　The rather thick blade of the saw has lost its teeth at the upper part and six square holes are cut into it in a row. Seventeen teeth are left now, which are splayed slightly to each side (Asari) for using it as a crosscut saw. A wedge-shaped metal collar called Habaki is set on the wooden handle and both sides are fixed by the method called Karakuri-dome on the fitting metal through the wooden nail hole called Mekugi-ana. Judging from the rather thick blade, it should not regarded as a saw for practical use, but as a tool for ceremonies. In the Gohomotsu-zue (Illustration of Imperial Treasures), a picture of this saw is shown, introduced as one of "the five treasures; an ancient saw."
