Thread: Help with a Koken Razor

Hello,
I am new here. I am completely ignorant about straight razors but I have my hands on one and cannot seem to find any information on it. The handle is black with either brass or copper bindings on the each end of it that has some curved engravings and a rivet in the middle. The blade says "Koken Companies" with "Solingen Germany" underneath it as well as some XXX patterns on each side of the writing. On the other side it has the word "Echo" but its in a cursive script so I'm assuming this is some kind of personalized engraving. Any idea of the age? Type? Value? Etc? Thanks
