There are a couple things to keep in mind though.
If you can't get a good knife really sharp using the basic Sharpmaker these sticks won't help you - like all sharpening methods - you need the proper technique.
The quality of steel is also a factor, these sticks are extremely fine so they are of little help when used on low quality steels.
These sticks do not remove much steel, they hone or polish your edge.
As to price, I paid less than $35 for two sticks - stones from Arkansas or Japan in the same grit/mesh/micron range are more expensive.
Note - As I go through my users, touching them up with the new sticks - I have seen improvement over all steels but, as I said before - the better the steel, the more impact.
I can get AUS-8 very sharp but, it doesn't stay that way. My BG-42 blades seem to love whatever the mesh/grit/micron rating is - one is a little neck knife by Kit Carson - it catches and lops off hair without touching skin.
Can' t wait to get to the S30V stuff - it seems that finer grain = sharper - is true. But, how long that lasts is the next question.
There is a very noticeably difference when used - knifes are razor sharp when used properly. Could shave with my Delica if I wanted.
Only ordered one and it will become a "pain" to use in the future, so will be getting another for use in the Sharpmaker. Glad I read the reviews as it lives up to them. never was I able to get a knife this sharp. I am not great at it is why I got the Sharpmaker kit and this stone just adds to the positive experience. No longer fear or hate getting a blade sharp - now razor sharp with ease.
Update 12.18 - got the second stone to make it a little easier. Went on a "if it has a blade, going to sharpen it" binge. Scissors, kitchen knife's and all my pocket and EDC's. The EDC utility that I use most often (Spyderco), I found that if it starts to get a little less sharp - give it a couple of passes with these stones and I am back to razor sharp. Very little effort to get it back. Never had a pair of Scissors this sharp - I just followed the instructions in the book. Again - worth the total cost of the kit and extra stones.
Return on investment is phenomenal. Close to mirror polish finish, stroke 30 for 5 minutes, stroke 40 for 1 minute seems to give the best results with a few drops of water to make the edge slide against the stone.
I thought I once knew what cutting meant. This little stone redefined that word.
Proven result on my classic chef knife. Effortless motion, vegetables are now properly sliced, just like in the old japanese Iron Chef video! It really make you feel that way, as the cutting stroke requires less energy, you are cutting faster with greater accuracy and precision. The result on D2 steel benchmade 710 is quite remarkable, no word can describe it, I guess the harder the steel, the greater the result. The stone came new with no chip. Haven't had the chance to use my paring knife yet, wonder if it would have as much wowness on it.
Now... The reason I gave this two star and not 4 or 5 is for a few reasons.
ONE: Value. I think this stone is overpriced. Just one single stone is worth approximately 1/3 of the entire system! And that is just for one! Two would cost you over $30. I just cant see why this stone is so much more expensive than the pieces in the original system. I bought one, and its not a big deal to just keep pulling the stone out and switching sides to get both sides of the knife. But I just cant see why they couldn't have sold this as a PAIR for $15. That would make this SO much better.
TWO: Packaging. When I received my stone from amazon I opened the padded envelope it came in and noticed that the stone was sitting halfway out of the plastic tube it comes in. I then noticed that the cap to the tube was missing and it was not in the envelope... I could have notified amazon and maybe received a replacement, but I really didn't want to go through that whole process over a cap. It was just disappointing. I fixed this by shaving down a cork to plug it... but still isn't ideal. I also saw another reviewer that their stone was loose and had a huge chip in it from being dropped.... so packaging is obviously an issue.
OVERALL: The stone does what its supposed to do. It gives your blades a professional sharp mirror edge for sure. But the value just isn't there. FOR ONE STONE. I pisses me off that two of these will run you almost as much as the entire system. And the fact that the packaging is crappy too just makes it even worse.
