8 1/4 ShurGrip

Hey there DR; Sharp edges are generally not good.Need to see a close-up pic of a mesh pattern.Otherwise impossible to give an opinion.
-Did it come with oil, and do you still have it? If yes,shine a lite across it at about a 45* angle and stir it up. Try a few different angles and see if you can spot the patterns that the metal filings would produce if in fact theyre in there. No streaks in old oil is a good sign.
