Oh the arguments I have had with saw owners bringing in saws that wouldn`t cut, chains smoked black from overheating,actually burning the chain lube oil until the chain is blackened. Get the argument the chain is only X numbers of years old and only made a few cuts since new, must be something else causing the no cut problem. Even showing them the damage to the cutters and resulting chain chassis damage they want to carry on the argument that the chain was hardly used. Show them a freshly sharpened or even a new chain and they can`t tell the difference other than their chain still has big cutters and not worn back much at all.
Wonder what the rest of these people's lives are like.
