Interesting topic. Instead of cutting the copper directly, how about cutting some vinyl or maybe masking tape? Then transfer the cut vinyl or tape to a copper clad FR4 board. Or maybe better yet, bond the tape or vinyl to the copper clad FR4 and then cut. Remove the unwanted vinyl or tape and etch the board. I have not tried this technique exactly, but have done a few boards with hand cut tape. If the etchant doesn't leak under the tape or dissolve the tape, it works fairly well. The trick might be to find the right tape, perhaps Kapton tape, or wide electrical tape?
