If you look at a bar that has a chain that doesn't fit well , wrong number, or has not been tightened correctly you will often find a ruff/sharp bent over burr along the outside edge of the bar. You can file the bur off and on some saws put the bar on upside down to even out the wear. A rolled edge on the bar can also keep the chain from cutting straight even if it is sharpened properly.
Yep good point. Normal wear will also put that burr on a bar eventually. I flop my bar over frequently to spread the wear. I also don't run a dull chain. It will build up a lot of heat and transfer that heat to the bar. Easy to see when the bar starts to "blue" or "scald".
