I bought this because I had some kitchen knives which had been poorly sharpened and needed re-profiling and this sharpening system looked to be a simple and fool-proof way of achieving a consistent edge angle. This system was recommended by "project farm" on youtube, and if you don't know about this guy you might want to check out his videos because he has some pretty useful reviews. It turns out this system is harder to use than it would appear. There is a learning curve. It is deceptive because it looks simple and obvious to use, but you really need to read the instructions (which are surprisingly complex) before use. Even after obeying the instructions there are still difficulties with using this system, but if you skip the instructions it's much worse. The main problem is that the clamp is very fiddly to tighten onto the blade and if not clamped perfectly, it can move around or even fall off. This would seem to be a simple matter of just tightening the clamp hard enough, but not so; the jaws have to be at exactly the right angle to grip the blade firmly. If the jaws contact the blade at the wrong angle, the blade can waggle up and down, making the clamp useless for achieving a consistent edge angle. For this reason, I would not recommend using this system on knives over 8" in length because you have to shift the clamp back and forth many times during the sharpening process for blades longer than this. Another thing to be wary of is that when sharpening, if you pull the stone back too far it can go past the edge of the blade, and if you don't notice this, when you push the blade forward again, you will jam the (metal) end of the stone into the blade, potentially creating a blunt spot. This can be avoided by taking care, but the exact position of the stone relative the edge is hidden under the handle of the stone, so this is not as easy as it might seem. Some people recommend clamping the bottom edge of the clamp to a bench to make sharpening easier and Lansky sell clamps for this purpose. I have found that this assists sharpening to some degree, but it depends on your particular sharpening technique and is a minor issue compared with preventing the clamp from slipping. However, once you get past all of this (practice helps) the system works superbly well. The stones are a little coarser than with other sharpening system which I really like because you can get a blunt knife sharper much quicker. For the record, the stones are as follows: Extra Coarse 70 Grit Coarse 120 Grit Medium 280 Grit Fine 600 Grit If you want, I think you can purchase an Extra Fine hone separately, and there's even a spare slot in the kit where you can store it. I don't think this is necessary for most purposes. There are "regular" and both 3 and 4 hone "diamond" sharpening kits available. I recommend the 4 hone "diamond" kit (the one I am reviewing) - the fourth hone is the "extra coarse" one and this absolutely rips into a blade and makes short work of correcting the most badly damaged edge. This stone will really save you time.Read full review

First impressions were it was cheaply made as the material is a very light alloy. However this is not an issue in use as it proves to be strong. Gave a great sharp edge to the knives i have sharpened, Would recommend also purchasing a stand which i believe should be part of the kit. I bought a c clamp mount which works well.

Very high quality IMHO. Better tools for sharpening are available but at a much higher price. Expect a lot of work if the blade is badly chipped, but the end result is perfect.

Easy to use and very effective. love it. Throw out all the other devices that wrecked our knives or tried my patience. Lansky diamond set is all I need now.
