Stihl and Husqvarna note levels of saws on their websites. That's easy enough for the newer ones. For the older ones, I would have to use other criteria such as
No "clamshell" saws made of plastic.
Built with metal crankcase containing 2 halves which support main bearings and contain a gasket in between.
Crankcase has a flat spot on top when assembled which supports the cylinder head, attached with bolts, and separated by another thin gasket.
Like that maybe?
So...will have to define better what makes a "pro saw" if the manufacturer doesn't specifically claim that designation.
Hmm
