I was running a 18" long x 6" deep x 1.1/4" oak board through my band-saw last night to re-saw it and it must have been case hardened. The wood bound onto the blade. I tried to pull it loose and ended up pulling the blade off the wheels and bent it. Anyway rather than spend 15 minutes trying to find another one and put it in (I was on a roll as usual) I decided to carry on the re-saw down the existing kerf with a Ryoba.
The double sided Japanese saw ripped through that oak like a hot knife through butter. I was really surprised how easy it was and such a smooth finish but won't be making a habit of re-sawing by hand (life is too short :-) ). Yes I do know that these sort of saws are intended for use with softwoods but needs must.

Anyway I'm more than happy with the Japanese saws I have.
