Thread: Need Some Help to Identify What This Is

mj,
The lighter side, shown with the insignia on the photo is much smoother and finer versus the reverse side, while smooth is coarse and has more grit to it.

Just a guess, but I don't think a really fine synthetic would be bound to a carb. So if I had to just guess from the pics, the "finer" side might be fine for setting a bevel. Unless you have a backup razor to use, I wouldn't run a shave ready blade over either side, unless you really want to send it out to be rehoned. If you don't care, go for it though Without touching it myself, it's too hard to say for sure.
