I recently bought a L&I J White 2 3/4" slick. Its been sharpened with a very slight radius to the cutting edge. I was wondering if this is right or if it should be sharpened square? What bevel should it be sharpened at? Also, as I have lapped the back of it there is still about a quarter to three eights stip down both sides that aren't square. Do I just keep working on it until its perfectly flat? Thanks for any advice.
