Review: Good price, good stone - So far I've been very happy with this stone. (I use this one and a 6000 grit stone). Good quality at a good price. Have had it for a few months and it is still nice and flat and even. Will update if time proves me wrong. Edit 6/15/09: I am now more familiar and experienced with stones, so I would like to add a few things. First and foremost, I still believe this is a good stone and at the listed price ($25), it's quite a bargain. I only wish they offered one that was a little wider. I've now tried some King waterstones - the standard for cheap but good Japanese waterstones. In comparison, this stone does not cut as fast as the kings at the 1000 grit level. The 240 side is fairly aggressive and cuts pretty fast, perhaps faster than king's offerings. Like most coarse stones (a notable exception being the bester 500 grit stone), the 240 side dishes quickly. The 1000 grit side dishes comparably at a more moderate pace. More importantly, I feel like this stone leaves a nicer finish than does a king stone at 1000 grit. As such, I recommend this stone in general, but I recommend it very highly if you are on a limited budget and don't want to buy any higher grit stones to finish on. The coarse side is probably one of the better stones in the 240 range on the market, but it is slowed down just a bit by it's narrowness. Neither stone individually is the best of its kind (though you'd have to leave desertcart to find some of the best), but taken together and considering the price, it's a good combo stone that could easily be either your only stone or the first two in your progression. In either case don't waste money on stones sold by knife companies - shun, global, whatever. They charge a huge markup compared to other companies based on brand recognition and people assuming that a company's stone is best for their knives.
Review: Worked well for me. - This stone may or may not be made by KAI as I don't know if they actually manufacture sintered abrasive bricks as that is not quite the same type of process as forging and machining steel). Kai certainly do brand it as their own. With that being the case I was willing to give this modestly priced stone a try. As with any stone technique and patience will have a great influence on the results. The 240 side is abrasive enough to smooth over the factory grind on Henckels Four Star and International Classic knives. My 5.5" Four Star santoku needed some work and the stone did a fantastic job of knocking down the rough burred baring a couple of tiny chips from ten years of frequent use. My santoku now has a fresh continuous edge without any burrs or chips. My most used knife is now sharper than new with many years of service ahead. My large santoku also Four Star wasn't as worn but it still had the factory edge from whatever coarse abrasive Henckels uses in their process. This stone is sufficient for removing this type of factory finished edge surface characterized by visible parallel striations in the steel. After using the 240 side the 1000 side will bring the edge to a very smooth edge. Beyond the 1000 side a 6000 stone can be used but is by no means necessary for anything I've ever cooked. The returns I've found beyond 1000 are quite diminished and more of an amusement than of any utility. When sharpening with wet fingers very sharp blades don't feel as sharp as they actually are against dry skin. There is a distinct difference between an edge of burr formed by using a steel vs the smoothness of an edge refined on an abrasive whetstone. I found that my knives were already very willing to cut paper with little effort without ever feeling as grabby or edgy against skin like I found with the results of using a sharpening steel. Stop working at the stone to dry and test the edge once in a while even if it doesn't feel sharp enough against a wet finger while you're working away at the stone.

### ⭐⭐⭐⭐ Great Value!
*by N***G on August 25, 2011*

Since buying this stone less than a month ago, I've ended up sharpening close to a dozen knives with it. I bought it on vacation, and before I got home to Toronto ended up sharpening a number of knives for my grandparents and relatives, many of which hadn't been sharpened in decades. I definitely appreciate the two different grits-- the coarse does a great job of removing any notches from the blade, and the 1000 grit side does a good job of honing the edge. My only complaints are that the stone seems a bit narrow. It would be a bit easier to use were it a little wider, like a King Whetstone. Additionally, it seemed fairly easy to score, and I've carved some of the edges off accidentally with my sloppy form-- though I can't compare it to other stones because I've only actually sharpened with this one. This stone also comes with a rubber holder for the stone that works well to secure the stone on a countertop. That being said, it only works when directly placed on a bare countertop. The first time I used the foot, I spent a half hour cleaning a mess of slurry off my countertop. I've thrown that bit in the garbage. Save yourself the pain, and use a wet rag to secure the stone instead-- it'll collect the slurry and save you the wash-up time. As a heads-up, the "instructions" are purely in Japanese-- but it makes little difference because there are a number of great instructional videos readily available on the internet. Without a doubt, this is a great stone for such a low price. You can't really go wrong.
