Thread: Difference in Carborundum Hones

I notice that the Carborundum Company seems to have made quite a few different barbers hones. I have never tried one but I have wanted one for at least a year and I'm thinking of putting in a bid or two on the bay this week.

So, for example, the different numbers I've come across so far are 118s, 177, F20, No 104, etc. I appreciate that some of these hones are of different sizes but are the grit characteristics the same for all of them?

Cheers,
