Anyone here regularly shave off a Spyderco UF? I've owned one for awhile and tested it a time or two. Curious if anyone here likes to shave off one, and what razor/s they use it with.
I hope replying to a post this old isn't considered bad taste. I have the full progression of Spyderco stones. Bought them for knives when I was still shaving with cartridge razors. The medium is considered 3000 grit, the fine is considered 8000 grit and the uf is considered 12000 grit. I have used the uf as a finisher before and it seems to me to be much much finer than 12000 grit. Maybe it was my newbie shaving technique, but it almost seemed too sharp. Maybe I'll use it again some time to check again. Sharpening on it is like sharpening on glass and it takes a bunch of passes for the stone to show any darkening at all. I have never checked my stones for flatness, but it seems flat to me. I usually clean it with Barkeepers Friend and it makes it look like new and makes it cut slightly faster. Once it loads with metal it seems to cut finer. You should never need to flatten it and don't need to use water. I tried it with baby oil once and it did not affect the stone (didn't lake the way it felt to sharpen on it though).
I had one when I first started straight shaving. It wound up having 16 hours of hard use on it before I mustered a shaving edge. Extremely sharp, and smooth, too. I stupidly sold that stone and some others. I regretted it so much I bought another. It's just not the same. I am convinced that the stones break in similar to Arkansas Stones, and until i match the hours upon hours on this new stone, it just won't do what I want. The first stone was quite out of flat, the new one is dead flat, so that isn't the deciding factor.
Thank you for the descriptions of all the stones used as a sequence. Like I said a few weeks back, I've always been curious about them. Your description of the UF as yielding a "too-sharp" edge makes me wonder if the stone might instead be used quite sparingly after the fine Spyderco--i.e., just a handful of passes rather than many passes in seeking to generate swarf.
That might produce good results. It really is a surprisingly fast cutter for such a fine stone. It really is underrated. I have never used the 3 inch wide version of this stone, I always used the 2 inch wide one. It might be worth it to get the wider one. I've read that stropping on newspaper after the uf can calm the edge down, but I have never tried it.
People used to say that newprint ink was abrasive and something like 30k-120k (depending on who you asked) if my memory serves correctly. I'll actually look and see if I can find any evidence of this under the scope at some point... but that was the argument for doing it a few years back.
