Hey i am new to this particular sub forum, and I just completed my first straight razor, so I am looking at getting some diamond (or cubic boron nitride) compound for my strop. But I dont know anything about it. I want as fine as possible so 1/4 micron, or .1 micron, but I dont know whether to get a spray or a paste, oil or water soluble, and I dont know anything about any of the brands. So I need help. Thanks so much
