I bought a number of razors over the last year, including razors listed as

1. 5/8 friodur
2. 6/8 Goldedge
3. 6/8 C-Mon HF
4. 5/8 Puma 81
5. 5/8 Wusthof Trident Standard

Anyway, I lately measured them, and they are all 11/16.

And then I checked my 6/8 LeGrelot and it's really 7/8. And I haven't even measured the rest of them yet. Very funny.

I couldn't figure out lately whether I liked 5/8s more or 6/8s and now I know why - they were all the same! Anyone else noticed that even official measurements aren't so accurate. I mean how hard is it to just plop he thing on a ruler?
