does it help? are they hard surfaced already? we use cat points, and arent getting very many hrs out of them, they told me they are 500 dollars a piece, when it gets to the point where it doesnt rip very well there is alot of iron still left on the point, its on a d11 so its a big point wide too. it never gets very sharp either its so wide that it always stays rounded. yes i rip with it curled under me the right way, any advice would be appreciated
