Here are some Pics ive made from the old and the new Special Coiffeur, both are marked as 5/8 but i Relatiy near 6/8, the older one wasnt honed very much until i got it so i think theres only about 0,2mm Left.
The older Blade is more massiv and not so fine like the new blade, also the new blade has a real sound like a typical full hollow, the older blade sounds like a typical half-hollow, its more the quiet type of Razor.
