I use SPYDERCO ceramic triangle SHARPMAKER rods..(if i can feel a bur = few strops on brown MED then a few strops on the white FINE - if just a touch up cuz i cut a branch - only FINE) ........ come in several grits from ultra fine to coarse to diamond.
I do NOT do between teeth on saw,ONLY CUZ I have never needed too
....that's me PERSONALLY
........I have only stropped the sides ( to get any burs knocked off) and have never ever had an issue with a real bent,burred,sharpened down, or a dull saw.
I would
GUESS
that if I had ever received a dull/burred/abused saw in a knife , I would atleast try to go between teeth.
P.S.
If you free hand sharpen, You can buy these stones separate at a decent price used on the Bay, And dont need the whole kit/sharp maker.
I could do with just 1 brown/Med. & 1 white/Fine , and never have a issue , unless I needed to re-profile a damaged blade.
