Those look like they would work well, I was using this old thing for a while,but the edge is very fine and really only meant for grass, the plastic packaging dulls it quickly.

Sorry to hear about the edge, I'd like to try to a scythe.
The serrations on the weed whackers allow a light touch with the foot to hold the packaging allowing for less chance of accidental trimming of the toenails.
