I have just purchased a Norton 4k/8k and am looking to lap it (although it looks pretty flat to me).

I read lots of threads and decided against the sandpaper route. I also don't want the Norton lapping/flattening stone due to it needing to be lapped sometimes and it being of no use for anything but lapping.

My conclusion is to buy the DMT 1200 due to it never needing lapping and its possible use on more worn razors before i move onto the 4k, and finally 8k.

The only one I can find at a reasonable price is: https://www.tools4trade.com/shop_pro...px?pid=1005196

Unfortunately its only 6" whereas my norton is 8". Is it possible to move the DMT over the bigger norton stone? I've always read that you do it the other way around but does it make that much difference? The 8" DMT is twice the price of the 6"

Thanks for any help.
