How about a generalized question about chains. 20-30 years ago it was easy...you cut wood and sharpen the chain and cut more wood. Now, there is skip tooth chains, regular chains, carbide tipped chains and so many makers of chain. I understand pitch, that has been around for awhile. I know what gauge is (I think) the thickness of the blades? My question, Is pitch used to keep chain RPM up? If so, why was the skip chain invented and what is it benefits? Is one brand of chain better then another? Is a carbide tipped chain worth the investment? All I own currently is a little husky 142, BUT, I have a trip to my father in-laws ;-) for wood and who knows what he is going to give me :red: I would like to know basically is there a difference among the chain manufacters or just grab an oregon std. chain or maybe a woodsman and call it good. All I am is a firewood user maybe 4 cords a year.
