No stupid questions...here is the Wikipedia answer:
From Wikipedia, the free encyclopedia
(Redirected from Burr (metal))
Jump to:navigation, search
A burr is a raised edge or small pieces of material remaining attached to a workpiece after a modification process.[1] It is usually an unwanted piece of material and when removed the process is called deburring. Burrs are most commonly created after machining operations, such as grinding, drilling, milling, engraving or turning. It may be present in the form of a fine wire on the edge of a freshly sharpened tool or as a raised portion of a surface; this type of burr is commonly formed when a hammer strikes a surface.
There are several contexts which this occurs especially during the knife making process when drilling say around the edge of the drilled hole or along a cut edge. Additionally with knife sharpening there is a burr at the edge which is created as the knife is drawn across the stone which needs to be removed to achieve the best edge.
I don't have a picture but I would bet that if you have ever got a metal sliver from a fresh cut piece of metal you actually know what a burr is.

If you've ever put plastic on something to grind it, then when you finished, you probably saw some frayed material hanging off the end of where it was ground. That's pretty much what a burr is on metal. It's weak, so you don't want it on your edge because it will just break off.
What does it look like? If you look at your edge in bright light and rotate it around, you'll see a highlight along the edge. You should see it on one side and not the other.
