Before I invest in them I would like some feedback from people who have actually used them. I know we all have heard raves from people be it a restaurant or a movie that just didn't live up to the hype. I need to hear from users if they noticed actual improvement in edge quality. Thank You.
 
Well worth it, as are the diamond ones. The UF stones provide a noticeable difference over the fine to me, and you can also see it if you have any magnification source. Three to six passes per side, corners & flats, just corners, or just flats, using just enough pressure to keep the blade steady is what works for me for most steels. ZDP-189 requires more patience or skill than I possess for the UF to be of any use to me.
Hope this helps.

I don't think they are that useful unless you are an avid sharpening geek.

I have the UF SharpMaker stones and also the UF benchstone.
The UF benchstone is popular with straight razor shavers. ( I just gave my straight razor 50 rounds on the UF benchstone. Tomorrows shave should be a good one.)
 
You did a double post in the Spyderco forums... but once again.

I think they are well worth the price. I can get my knives to whittle hair on the UF. I can't get them to do that on the Fine. :eek:

I posted this before but it never hurts to have visuals. =P

BTW the steels are VG-10 on spydies and CPM S30V on the BM 558 and 154CM on the BM 14210
 
stropping with what. the UF approximates a 3 micron stone. chromium oxide is about half a micron.
 
I used to strop with three grades of lapping compound (got the cans from a portable valve seat resurfacing kit - "valves" as in 14 inch diameter, not automotive - got me what "grit" size, but the No. 3, the finest, could be used to polish glass, if that is an indicator (?)). Ran out of the finest stuff and am now trying various diamond pastes.

The issue with the UF stones was that that the surfaces all had imperfections that could be felt with one's fingers, i.e. the surface was not truely flat (and "flat" means "smooth", a subjective description). Further, minor changes in sharpening angle appear to be compensated for in the relatively soft leather/cloth of the strop, while the ceramic gives no such compensation, i.e. the ceramic results in a more irregular edge (that's my theory).

As such, stropping gave me a better edge.
 
Check your stones before you buy. Mine had circular saw marks in the surface and had a slight twist to the stone which means no way of getting a flat surface to sharpen on.

I rubbed the stones together for a good bit of time, to flatten them.

But, they never became truely flat.
