I use fine grain wet/dry sanding paper. Cut a trip the width of the slot in the edger and sharpen the inside edge with this.

Sharpen the outside edge either with a sharpening stone or bigger piece of the paper, remembering to follow the curve.

It can be a bit fiddley but saves buying a fine jewellers file or some such.

Hope this helps

I used a small diamond tip dremel tool on mine yesterday and it worked a treat. You have to have the right angle and be very quick.
