Resharpening Rotabroach cutters

[Sperstad]

Hello.
Does anyone of you know how to re-sharpening a Rotabroach cutter easily? I`m not interested in buying a expensive machine for this job. Is it possible to just use a Dremel tool, and re-sharpen the cutter by hand?

you can get away with sharpening once maybee twice just make sure you grind in the same way as it would be done on machine, use a white wheel and be steady..
