Hi Jon, Depends on your cash flow. You could get a used sharpener somewhere off the web somewhere such as http://www.labx.com/v2/adsearch/resultsnew.cfm?sw=sharpener&mr=25&te=cat , or http://www.medwow.com/used-microtome-knife-sharpener-equipment/63.med but sharpening knives is a pain IMO and steel knives present more of a safety hazard. I would recommend a sharpener that uses the glass honing plates. You would also need the coarse and fine abrasives.
Personally, I would opt for a low profile disposable blade holder that fits your 820. Low and high profile refer to the size (height) of the blade. We use low profile for paraffin block sectioning and high profile for cryostat sectioning. Brett Brett M. Connolly, Ph.D. Principal Scientist, Imaging Dept. Merck & Co., Inc.

I am not histo tech, I did all my sectioning in a plant research lab, but now I find myself needing to learn more about histo type methods. We have microtomes, AO 820's, and we have a bunch of donated knives. I need advice about whether it would be better to find a knife sharpener and use the microtome knives we have, or check into getting a disposable knife holder. When I was sectioning, we just used a simple razor blade holder. Now I see references to high profile and low profile blades and holders, and I don't know the difference. Anyone willing to help me out?
