Okay...Kinda sounds like they are re-brand Chinese chain then. Don't get me wrong as there is both excellent and extremely poor products coming out of China, just depends on the manufacture. My problem right now is the darn 100% metal tariffs here is driving all metals thru stratosphere. This is also limiting the styles of chains with some dropping the safety chains that home owners needs to be using.

I may just stay with the TriLink chains then. And buy Oregon as needed. I know TriLink are fairly good chain for most of my customers and myself. It just that I not able find it at a reasonable price since I quit the distributor I had. Yes they are lower quality but most of my customer have a bad habit rocking their chains in the first place and no chain other than carbide handle rock very well. But even a carbide chain can be dulled.

And Norm I have heard of the Power Sharp system but never have seen it here in the shop.
