Rotary blade sharpeners?

My reply from discussion of Aug.8 when same question was asked:

" Are you asking about the new orbital sharpener or the tri-sharp one that has been on the market for several years? I have used the tri- sharp 45mm one to prolong the life of rotary blades - I usually wait until I have several to sharpen and do them altogether - labelled 'as sharpened' in a container. I also stocked up on the refill disks whenever I saw a good price on them - it is getting difficult to find a supply of them now - I am still looking for a supplier of the 28mm size refill disks. As for actually having to change the sharpening disk for a fresh refill - that hasn't happened yet - it has lasted for a very long time. The orbital sharpener uses a diamond grit sharpening wheel (fine or coarse) and replacement ones are sold separately (about $10) or in a pack of both grits (about $16). The orbital costs approx twice as much as the tri-sharp but it does accommodate both the 45mm and the 60mm sized blades - they are also working on a 18mm and 18mm combined sharpener size. I can't comment on how well the orbital sharpener works on renewing a blade but considering how well a diamond grit nail file works and how long they last - I'd say that the extra cost would be worth it in the long run." jennellh

Thanks Jennell! My apologies for being redundant. I don't get to read the group as often as I'd like.
