Comments about Nicholson Half Round File and Rasp:
Used it to rasp and shape ash gunnels on my cedar strip canoe; did a decent job of removing epoxy and fiberglass sticking above the gunnels and brought it level to the gunnels quiclky, also used the finer file side to start the rounding over process,which I then went to a finer file, then sandpaper. For [$]pretty tough to beat.
