SP302UF: Spyderco 302UF Ceramic Bench Stone, Ultra Fine
Because Spyderco's bench stones are flat and broad they are highly effective for honing wide tools like plane irons, chisels, large blades, woodworking equipment, even ski edges.

After many requests, Spyderco is now manufacturing an ultrafine-grit 2" x 8" x 1/2" bench stone. Ultrafine stones are ideal for professional polishing and finishing and can tighten the steel's sratch pattern bringing an already sharp edge to an even keener level. The stone comes packaged in a rigid polymer black storage case complete with non-skid rubber feet for tabletop use. As with all of Spyderco's ceramic stones, use our benchstones dry without lubricants or oils.

To clean: wash with fresh water and scrub metal particles from the stones with a plastic scouring pad and abrasive powered cleanser.

good but,.....
Stone was not flat along the longer (8") dimension. Needed about 1-2 hours on a diamond stone to get it flat. Across the shorter (2") dimension it was flat. Given how most would use the stone might not be an issue. Same non-flat was found on the medium bench stone but not to the degree of the ultrafine. Given the effort to flatten the stone I doubt it will require re-flattening even after years of use. In use it is only for the final honing, surface loads quickly requiring cleaning. It is not for edge grinding will take too long. Puts a mirror microbevel on a properly sharpened edge.

Quality Ceramic Stone
I was hoping this stone would match the finish produced by a Case "Moon Stone". It does not, it is slightly coarser. The problem with the "Moon Stone " is that it's only 3 3/4" long; hard to use when sharpening a long blade. Plus, it's not available any longer... I tried the Spyderco Fine (it will hone an edge that will shave hair), then the ultra fine ( it will shave hair even better...). I'll be ordering the Med. as well. The ulra fine I purchased was a little too thin to use in the holder/case (not a big deal). The Fine was ok on thickness. Both are flat and cleaned up easily using a bar of lava soap and water. Also, both cut well. If Spyderco starts making a extra ultra fine I'd get that as well.

Prefect final stage stone
Give my blades a mirror shine edge. The stone sets at a prefect high to allow free hand sharpening with ease. Of coarse, makes my knives razor sharp. A super purchase if want to take your knife to the next level.
