Found some razors in my Grand-daddy's attic...Please help!

[CircleOne]

Hi everyone!

After my grandmother passed last year (Grand-Daddy passed 15 years ago), I was going through their attic, helping my mom clean stuff out, and I stumbled upon two straight razors, and a single bladed razor. I would appreciate any info anyone can give me on them. I don't know anything about razors, but the maker's mark and company names are still visible on all three, so I thought maybe someone here could give me a hand.

The first one says Geneva Cutlery Co. Geneva, N.Y, U.S.A. printed on one side, and (partially obscured by rust) ...OGENEV above what looks like a harpoon crossing an anchor, with the word Navy printed on the other side. Pictures:


The next one says Dixon Cutlery Co. Germany on one side and what looks like (lxlLlDl) Trademark written on the other side:


And finally, the single blade razor has what looks like Rolls K Razor 35 7 Made in England on the top and Best Sheffield Steel engraved on the blade itself:


I think my mom is looking to sell them, if they're worth anything, so anything that you guys can tell me about them, or their worth, would be greatly appreciated.

Thanks so much everyone!
