We just got done explaining the difference between water-based stones and those based with oil. Well, this last section also plays a role in determining which style you prefer. But, either way, it is not as if there is a clear-cut loser in this case. The reality of the situation is this; sharpening stones need to be lubricated because if they are not, they will lose their effectiveness and will not be as efficient. But, the manner in which they need to be lubricated is going to be different between the different types of stones.

I purchased this set together with the 400/1000 grit stone assuming that some of my knives were quite dull and would need work on a coarse grit stone. Premium Whetstone Sharpening Stone 2 Side Grit 400/1000 | Knife Sharpener Waterstone with NonSlip Rubber Base & Flattening Stone. This is my first wetstone. First off I tried to sharpen my Chicago Cutlery boning knife. This knife is nearly thirty years old, has been abused in may ways and was quite dull. It was very difficult for me to get a burr on this blade, which I attribute to poor technique. Next I moved on to my Henckels Professional S paring and chef's knives. The paring knife was moderately sharp and was modestly improved after working over all three grits of stone. It would cut paper but again it was difficult to develop a burr with this blade. Undaunted I switched to the chef's knife. This knife is twenty years old and has never been professionally re-sharpened. I have sharpened it twice with a Lanksey sharpening system which marred the finish but did put a good edge on the blade. Lansky Standard Coarse Sharpening System with Fine Hones. The chef's knife was moderately dull and had several pits visible on the cutting surface. I modified my technique for passing the knife over the stone and worked the chef's knife over the 400 grit stone aggressively and eventually I was able to get a burr to form from the tip of the knife all the way to the handle. From there it was a simple process of reforming the burr on the 1000 grit stone and then finishing on the 6000. After sharpening, the chef's knife easily and cleanly slices a tomato with very light pressure and is in my opinion very sharp. Not sushi knife sharp but more than enough for the chopping and slicing I expect of it. I'm looking forward to going back and working both the boning knife and the paring knife over again. Don't expect a good result from this product the first time you use it. Watch videos on using a wetstone, expect to spend at least twenty minutes per knife at first, and practice forming a burr. If you can form a burr, you will be able to successfully sharpen your knife.


We begin our whetstone sharpening process with a 400 grit stone to shape the edge of the blade and develop a burr along the edge of the knife. Once the shape is set and we have a burr along the full length of the knife we move on to the 1000 grit stone to refine the edge and begin removing the burr, followed by the 5000 grit fine stone stone to give a beautiful sharp edge on the blade. We finish off each knife on a leather stropping block which removes the final remnants of the burr and gives a strong and lasting edge.
Nothing can be more annoying than using a dull equipment in the absence of the best sharpening stones. It will make you exert more force where you actually need to use the sharpness of the blade. The ultimate result will be that you will end up having muscle pain which will take your annoyance to an infuriating level. To avoid this frustration, you should always keep your blade sharpened. That is where top quality sharpening stones can really help you out.
These are very popular stones. 8" Dia-Sharps have a single grit per stone making them more expensive, but at 8" by 3" they are wider than the 8" DuoSharps, offering a good working surface. The 8" Dia-Sharp line also has the widest range of grits available from DMT, with extra extra coarse, medium extra fine and extra extra fine options not available in other sizes, so it is good line to consider. One coarse and one fine stone is a good starting point.
I bought this wonderful knife on faith. I was told in March when it would ship. I received emails alerting me that my knife would be arriving as promised. It came early, thanks! Tthe quality and feel of the knife exceeded my wildest dreams. I lived in Tsubami ahi where knives are hand forged. This has a place amongst the best. I have it on display for now as I view it as a supreme work of art.
You've acquired a good chef's knife, you're using it almost daily to make tasty dinners for the family, and it's stored in a nice knife rack or a magnet for safekeeping. So why stop there? Keeping that knife's edge fine will make cooking not only safer but, let's face it, much more fun. Whether you've spent £150 on a high-end knife or under a tenner on a dinky paring knife, keeping it sharp is crucial.
