I'd grab that bow saw for a limb anyday. Both look like a joy to use, interested in the performance of the frame saw, the raw cut surface can be a finish all on it's own!
Thanks RyanGi, SplinterGroup, Pottz! It's amazing how well and easy they cut. Both perform well. I made them out of pine using a 1" bandsaw blade, 6 TPI. The teeth are so big that it's easy to sharpen if need be. Both cut on the forward stroke.
