Thanks men-I'll take your experiences and advice into consideration. Glenn, I got one of the "good" Norton 4k's before the production move. It doesn't have the rough skin that apparently some had to lap through. That said, I'm not sure it improves a Chosera 1k bevel all that much-I swear that green brick can hone like a 4 or 5k with a few sets of super-light strokes after bevel-set!
