there are some griffon 60's on e-bay now. be careful as some of the blades have been oversharpened. make sure the edges are straight and parallel to the spine. I am referring to the razors that are real cheap. $10 to $25.
I was looking at some of those, but some of them are in such bad shape. (One had half the blade broken off, another had an inverted smile).

How would you be able to tell if it has been over sharpened from the pictures?
