i would say please don't learn honing on your Waker. i assume they are costly razor's.
buy some cheap old ugly bay razor and your norton hone and learn how to hone. then you should be ok.
Now about your original question
Norton makes micro chipping
This is true
If you do make more strokes then you should be. edge will brake down. In some razor's it will happen earlier then others . but this will happen in all of them not just wacker's.
to avoid this you will need to have better quality hone.
by the way 16k shapton does worse if you use more then you should
this is another factor HAD people constantly looking for better natural hones.
Escher, coticule ,Japanse hones.
hope this helps.
