All good advice, but I'm fairly experienced at sharpening and not looking for a magical substitute for doing it, just came across an opportunity and looking for experienced input. As I said I don't cut wood in large volumes, so I don't get in to strange situations that cause me to worry about ruining a chain. As far as the money and investment side of it, I can get this chain for 35 dollars... Hardly an investment and actually not much more than a standard chain. I'm just curious if there are some hidden issues with them in general. The fact that they chip is a hidden issue I never thought of and is very helpful. Hitting a nail is another one, I figured it would cut right through a nail (one of those myths apparently).Carbide chain has many myths attached to it one being you can cut anything with it.
For the money and time would it be better invested in learning how to sharpen normal chain efficiently than looking for a magic mythical chain that never needs sharpening? absolutely.
Also a big part is knowing what you can and can't cut if you see dirt clean it off if bark has dirt in it use an axe to cut it away at your cut. There is no magical solution as yet to cutting dirty timber.
