Some time ago I picked up a cheap sharpening system from China. IT Was Rubbish. I got my money back but was left with a set of flat plates now devoid of any grit. With a bit of wet and dry they have found a new life.
They come with a two piece clamp having 4 holes to allow the guide to work at different angles. It also had a cheap plastic handle but I mounted then on a frame I knocked up as I proof of concept but work good enough as is. This clamps the blade in pace but can be turned over with out upsetting the sharpening angle. The original plates are now used with a bit of wet and dry paper held in place with double sided tape.
Might not be the best in the world but does give some one with no skill a chance of a sharp blade.
