Damn. I really like them both. I owned a 'Japanese Saw' that was shaped like a bread knife. I bought it when I was rebuilding a table that had pegs instead of nails or screws. The blade was so flexible that I could lay it on the surface and trim a pin off exactly at surface level. It was wonderful.

Yeah, I've seen a lot of Japanese saws that look amazing. They are very versatile for making a lot of works. That one looks awesome for that kind of cut that tends to be annoying with regular saws.

It looks awesome. Good tools are worth a lot and pay themselves over and over.
