Hello

I'm still trying to decide which razor to buy as my first, which is better Carbon Steel or Stainless Steel? I would think stainless steel because it shouldn't rust depending on the carbon content, but also I would think it would be harder to sharpen! I have one more stupid question, I see a lot of razors listed like 5/8 or 6/8 are thy referring to blade size? if so 6/8 should be 3/4" correct, just wondering.

Thanks
