Chainsaw Repair

Kevin, I don't think you heard a raving review about the chain, at least if its the same stuff as up here, but the files are supposedly cutting as good but lasting longer then a safe edge.
My last batch of of ten boxes or so save edge files aren't as good as they were a year ago.Still better than anything else I can find.
I have 2 boxes of laser files in the mail as we speak.

I saw report on AS a with a couple of jeweler types discussing harder than steel files that would last "forever" and they mentioned industrial ruby that you could get a 7/32 for about 75 dollars. At 20 bucks a box for files, 75 dollar file would make sense if I didn't loose it.
I know the high end chain filers are using different ceramics for finishes but they may be too fine for every day use.

Has anybody here experimented with non steel or HSS and harder files, I am looking for that magic bullet.
