I've had quite a few Dovos over the years & my own experience seems to indicate that the steels do apear to behave differently as regards my own shave quality & ease of sharpening ect.I recently gave a NOS dovo 5/8 special to my stepson as it didnt work for me althought I did get it to take an excellent edge.
At the moment I have got 2 Dovos a Begersher Lowwe 5/8 & a cheap 5/8 super Bismark both of these work very well for me & Have been easy to hone & keep thier edge the super bismark is a half hollow grind that gives me excellent shaves & has become somthing of a favorite for me.Both of these blades just seem to work for me better than the other dovos I've had the pleasure to own.
At the end of the day it has just been trial & error in the endless quest to find my own personal favorite& this is what keeps me looking out for more razors.Paul
