has anybody tried the self-sharpening kits for chain saw chains? It looks
like some kind of bracket to hold the blade, and a hand file to sharpen it.
I bought a cheap McCulloh chain saw and the chain got dull after only a couple
hours of use, and i bought a new chain, but this one got duller even faster.
perhaps it's an oil flow problem...dunno.

So i don't know if it should take both chains to a sharpening shop, or if i
should go buy an expensive high quality chain (which brand?), or if I should
buy the hand sharpening kit?

Thx,,,paul
