I have a couple of 6/8 blades (Dovo Bismarck and Gong Cutlery which has a slightly longer blade than the Dovo) but when I tried the Filly 7/8 doble temple, I was almost overwhelmed with the overall size of the razor and blade.
Is there that big a difference between 6/8 and 7/8 or is that model of Filly atypical of a 7/8 blade?
