I have found that Japanese saws vary hugely in quality. This saw is one of my absolute favorites. It cuts beautifully both when ripping and when cross cutting. It leaves surfaces as smooth as a planed finish without obvious saw marks. I would like to get another one or two by the same manufacturer but I have no idea who that may be. I bought this one quite a few years ago from a supplier who no longer exists so I can’t ask them .
I’d be grateful for any help in identifying the maker.
