Those are 'vey' cool saws; a few bowyers use them, though they admit adjusting to 'pull' instead of 'push'. The saws make an excellent cut, very smooth to use without the tear out that usually accompanies the standard 12 point hand saw. I believe they are also shown in the Garret-Wade catalog.
SSQ sent me the link to the Garret Wade catalog, and one to a Fine Tools website so I could see what to look for. The saws I got have the bamboo wrapped handle and they're double flush cut so they won't mar the floor as he's cutting the door molding
