C85 out the box VS filed with a 5.5mm (7/32) file. It's not worth trying to replicate the factory grind. This was sharpened 30 Degrees, 10 Degree down. Depth gauge set at 0.65mm (0.25) Wood is dry stringy bark eucalyptus.
@@ChainsawUsers Honestly don't know. The whole video has 3 cuts with the new chain and 4 with the sharpened one. The average is even more in favour of the round filed chain.
