So in the last couple weeks I have developed an interest in straight razor shaving. I started poking around online and came across the PDF booklet "The Art of the Straight Razor Shave" by Christopher Moss. I read through it and eventually ended up here. I mentioned my interest in straight razors to my dad, and told me he had an old one that he could send to me. He never used it much and I don't think really knew how. It arrived today and looks like this:

I'm fairly certain my dad bought it used. The box (which looks super old) says Geneva Cutlery Co. Geneva, N.Y. But on the shank I'm pretty sure it says Golden Mule Cutlery, Chicago. It's kind of hard to read.

My first question is, is this something I should use? Having it be free is awfully appealing. I don't know anything about straight razors, so I don't know if either of these brands means anything.

Second question: If this isn't something I should use, where should I start looking, and if it is, what other supplies should I pick up and from where? As far as I can tell I need a strop, brush, soap and a cup. Possibly a barber stone?

Any help is greatly appreciated.

Thanks a lot,

Luke
