I noticed on the Nassrasur site a video clip by Norbert Schick on sharpening a razor. He begins with lapping the Norton stone using sand paper and a glass sheet. How often do you have to take this kind of action on a Norton?
I also have a 15K Shapton stone. Do I need to lapp it also? if so how often do you recommend?

To get it back to it's baby smooth state you need to lapp it with super fine powder and a lapping plate or some other suitable system. I have the Shapton compact lapping system, but there are other less expensive solutions.
Grrrr, I cannot find this links... jmsbcknr, can you please post this link too, if it's not the same video. thanx
I have been using my norton for two years now and I've probably sharpened over 30 razors on it and its still as good as new. I think the answer to your question depends on the user and his technique. When it needs to be lapped you'll know it because you will start getting inconsistant results.
Here is the web site I have been looking at. Check out the videos http://www.nassrasur.com/norbert/norbert.html

The Norton will not need to be lapped very often. It really depends on the number of razors that you hone.
Use the sandpaper technique a couple pf times just to see if the hone is dished. What you are looking for is a uniform appearance after 10 X pattern laps.
Be sure to put the hone under running water and rub off the abrasive particles that are embedded from the sandpaper.
