I own the Spyderco system, and I think it's about the all-around best sharpening system going. Easy to use, not at all messy as it requires no sharpening oil, and will truly get a knife (or other cutting tool, very versatile sharpener!)shaving sharp.

I know many reviewers of the ultra-fine stone are complaining that "they only got one stone." Jeesh! READ the specs! The catalog clearly, clearly states that they are sold INDIVIDUALLY. "Individually" signifies "one by itself", folks.

Now, for an actual review of the ultra-fine stone itself... (how's that for new and different, huh?)

The UF stone works exactly as advertised. It will put an unbelievably sharp edge on your blade! Now understand, with just the medium and fine stones included with the Sharpmaker, you can get a blade sharp enough to shave hair. However, this UF stone takes that sharpness to the next level, resulting in a blade that can be very lightly slid along your arm with next-to-no pressure at all and the hair just flies right off. It will, with just a couple of strokes, take a sharp blade to the "Samurai test" state of sharpness... putting the blade against the hair at the back of your head and attempting to move it down. If it catches and doesn't move, it's sharp!

I'd say these stones are a worthwhile purchase IF you're only satisfied with the sharpest possible edge on your knives. Like me, obviously, since I bought them and love them!

If you have the spyderco sharpmaker system and are one of those people who absolutely needs to have the sharpest knife around, this is the final piece. My knives were already sharp enough to cut a piece of paper width wise, so knowing that there was something out there that could make the blade even sharper... well that was just too much to be able to resist. To be honest, it's not a drastic increase in sharpness, but it's definitely noticeable. Buy two quantities for a complete set.

The the first couple reviewers- if you'd done any shopping around at all for these stones, you'd realize that $15 is about the going rate for 1 stone, not the set.

As long as you have a 204 sharpmaker this is a must have add on to an already great set. After the fine stone you can move over to the puppy and really take that blade to the next level. If you are working on CPM m4 or ZDP 189 make sure that the edge highly refined on the previous stones or you will get nothing the stone doesn't have enough bite to really affect the bevels of steel in that hardness range, but that should be a given since it is an Ultra fine stone. This stone with minimal effort can put a near mirror like finish on my ZDP delica in 5 mins on the 30 degree side(after the bevel is set with the lower grit stones) It also makes quick work on the 40 degree side of taking a pretty sharp knife and taking it to the next level(for edc blades). Even being as great as it is, i still do see minor edge improvement after some very light stropping on 3 micron chromium oxide(this may be a fault in my technique on the sharpmaker) All in all I find myself using the sharpmaker even more than my whetstones since i added this to my collection. Also it allows me to hit the edge on recurved blades(ie: kershaw shallot) with a high grit ceramic that is fixed in place rather than held in had like most are. Giving me much better control over the edge geometry.
