The thing with the carbide chains is they can never be as sharp as the standard ones, that is why they are so much slower. Carbide while tough as far as wear goes is also brittle hence you can't put as fine an edge on them.

Where they really shine is in cutting very old, very hard timber. Like the teak pilings and timbers under many of Melbourne's older wharves - Melbourne Ports were an early user of carbide saw chains.
