Another vote for Fish's. When I ordered mine, you talk to the owner and maker of the saw. He will even re-sharpen if you pay the shipping, just schedule it during the off season.

I don’t think so, I have sharpened mine with a file after running into some sandy ice beaver trapping.
reason asked is we had some made and they seemed to be softer than a nils which was what they used for the pattern, but the sharpening and set was a trick to figure out
