I have used a DMT 325, a King 1000/6000, an MST thuringian and a translucent white arkansas for over 100 razors, not including razors I have sharpened for other people and for myself - I've had nothing but good results. Haven't even used a Norton - yet - but I have ordered a 220/1000. Undoutedly the 4000/8000 is good, going by what people say about it. A Merc is good for a first car too - I could only afford a Ford, though...

Regards,
Neil.
