On most of the chisel ground edges I have seen the bevel is wide enough to easily be able to line up and lay it on a benchstone at the correct angle(oddly enough, like a chisel). You sharpen it to a burr and cut the burr off with a flat to the stone (or slightly elevated) pass on the back side. Works great, especially on tantos. However, I haven't tried that method on a huge chisel ground recurve (a la Commander), I imagine that will take more imagination.
