I had my first shave with a Greek Bic this morning and was so satisfied that I thought I'd share. Overall, it compares very favorably to a Swede in terms of sharpness and smoothness. It performed better on my chin than a Swede- got a Feather-like BBS there without the irritations that Feathers give me.
Cheaper than Swedes and Feathers, sharper than Derby's and just about as smooth. I'm very impressed. I wonder how many good shaves I can get from a blade, but at this point I am ready to start using these over the Derby's.
