Though "whetstone" is often mistaken as a reference to the water sometimes used to lubricate such stones, the term is based on the word "whet", which means to sharpen a blade, not on the word "wet". The verb nowadays usually used to describe the process of using a sharpening stone is to sharpen, but the older term to whet is still sometimes used. The term to stone is so rare in this sense that it is no longer mentioned in for example the Oxford Living Dictionaries. One of the most common mistaken idioms in English involves the phrase "to whet your appetite", too often mistakenly written as "to wet". But to "whet" quite appropriately means "to sharpen" one's appetite, not to douse it with water.
Your stroke can be straight or circular, from "hilt to tip" OR "tip to hilt," whichever is more comfortable. If you're using a small portable sharpener, stroke the blade in nearly a straight direction. Remember to always cut into the stone and never pull or drag your edge backwards. The blade edge should face in the same direction as your stroke. So, you're essentially moving the metal away from the edge. We recommend the circular stroke as it helps you maintain your angle instead of having to find it every time you lift the knife from the stone.

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.
