Japanese back saw 'dozuki.' This is an antique, fine tooth Japanese back saw for fine cuts. It has not been sharpened in a long time, but is a serviceable tool if sharpened. It comes with an old handmade blade cover in wood. It is a lovely tool for use or collection, rare to find in such good condition. Sharpening here will cost extra, but it is a beautiful tool. I continue to use the same such tools in my own furniture making here in Japan.
