I have rounded the edge of all my stones except my shapton stones.
I don't know why I haven't rounded the edges on my shaptons lol maybe its because of the size, I actually didn't even realize I hadn't round them until this thread lol

If you bought your Nortons from Howard at TPE you should be good to go. It's been a while since I've been to his site, but IIRC he did offer a lapping service at one time, probably still does.
FWIW, 98% of vendors do not pre-lap hones (especially Lee Valley), so you usually have to do it yourself.
I chamfer or round the edges of all my stones so that if i accidentally raise or lower the blade it doesn't come in contact with the sharp edge. I am in the (ounce of prevention group).
Remember, the flattening stone will need to be flattened ventually with 400 grit sandpaper and something very flat like thick glass or a DMT lapping stone. Since you need to lap them, I would take it back and just get the DMT 325 right from the start since you can replace that flattening stone altogether. They are a bit pricey though. Also, Norton recommends lapping after every 400-600 passes. Make it less i you tend to add anything more than nominal pressure while honing. Good luck :)
