Square peg, round world.
I've got a couple of two-man saws and one one-man saw. I have played with the one-man saw a bit. I need to do more work to it, but it does cut ok. I believe the thin, straight two-mans are felling saws, and the wider, bellied saws are for bucking. You can make a spider with a block of wood and four screws. Cut it into a diamond pattern and put a screw at each point, with just a little bit of the tip of each screw sticking out. On a flat surface, using a feeler gauge, adjust one screw on the long axis of the diamond to your preferred set.
