I had a few older Dovo's from (many) years ago.
Stopped shaving with an open razor awhile back,..but then decided it was time to try it again.
I have a decent Silver King that I started with ( the Dovo's went away ), and an old Wade/Butcher that lived up to the last part of it's name....shaves well, but too big for my face.
So I broke down and bought me a Bismarck from Vintage Blades, and it came honed ,Lynn did the work, and my god,..what a very nice smooth shaver !!!!
The only drawback I found was when I went to give it a couple of strokes on the strop, post shave
The backstrap has some sharp edges and as I rolled the blade, it left scratches on my nice strop.
So beware lads ! It's a fine shave,..but be mindful of the jimps !
