What is a plane iron mark?

[Matt Woodworth]

I guess the subject says it all. I saw somebody say he uses a cabinet scraper to remove plane iron marks. What are they?

Hi,

Sometimes the corners of the iron leave lines, I guess this is what that person meant. I prevent this by giving the corners a couple of passes at the end (on the last sandpaper, oilstone, waterstone, etc). I've also had my planes leave very small lines as a result of the edge having an imperfection (from use). All I do is pull the iron out and work on the bevel until it is perfectly straight again, then hone.
