i quit cutting yesterday due to a dull chain..hit a rock....i have 3 chains all are dull now....so i took em to the shop this morning...(shop ive never been to)..they said we can do one for u right away..and the other 2 tommorow..i said great..that will get me back in the wood today...they sharpen the one and im on my way....get there and as soon as i put the saw in the wood..its dull as hell.i only got to cut like 4 25 inch oak rounds before i decided it was too much work..and too hard on my saw....man was i pissed....he had no idea what he was doing on that bench grinder apparently....i gotta get better at sharpening my own chains to avoid this kind of thing
