Sharpening stones include water stones (whetstones used with water) and oil stones (whetstones used with oil). Water and oil provide a lubricant on the surface to eliminate any extraneous friction, improve sharpening power, and prevent damage to the stone itself.
A couple reasons. Soaking stones are porous. If not soaked, water will seep into the stone and not stay on top. You'll constantly be adding water. Soaking also softens the binder a bit, releasing more grit which expedites the cutting of the steel and also helping to prevent the stone loading up.
Some whetstones can even be stored in water, but you will want to double-check that you can with your particular whetstone. Medium to rough course stones can usually be left in water, while fine or finishing stones shouldn't be. Added Tip: Each whetstone has the grit number labeled on the block.
While some stones – like those made of diamond or ceramic – can be used dry, they still usually benefit from a little water. Soaking the whetstone is important because it helps protect the stone from damage and wear. Sharpening your knives with a dry stone won't hurt the knife, but it will damage the stone over time.
Oil stones are intended to be used with oil, or rather oil is the lubricant that will work best. You can use other lubricants, including water, on most types of oil stones, it just doesn't work as well.
Your stone will require lubrication to function well. In the sharpening phase, we do not recommend any current WD-40® Brand Products although some may be used later for storage & protection. For sharpening stones the lubrication can come from water or oil.
Does this mean that non-water stones should be used 'dry'. No, this is also not the case. Instead of water you could also add a couple drops of oil to the surface of some whetstones. This mostly applies to very hard natural sharpening stones.
Plant-based edible oils. Olive, peanut, rapeseed oil, etc. Bear in mind that such liquids are highly viscous and can lead to clogging of the sharpening stone surface.
Push the point you want to sharpen with your fingers. While keeping the angle and pushing the point with your fingers, stroke the blade until it reaches the other edge of the whetstone, then pull the blade back until it reaches the edge of the whetstone. This back and forth is counted as one stroke.
Soaking stones often provide a better feel and sometimes better results than 'splash and go' whetstones, but are not quite as quick to use. 'Splash and Go' whetstones just need water splashing on them.
The materials will start to disintegrate and your stone will be rendered useless. This is more typical of synthetic stones than it is natural ones. There are some whetstones that may crack when they are left underwater for long periods of time. This usually happens if the water starts to freeze.
Whetstones will crack or break from too much weight being placed on them. If you store multiple on top of each other, the lower ones have a high chance of cracking.
Whetstones have an average lifespan of up to six years. If you use yours less often, you can expect to get more use out of it. Every time you sharpen a knife, it wears down the center of the stone. This wear and tear will eventually cause the stone to break apart.
Waterstones and oilstones wear at greatly different rates: The softer of the two, waterstones, dish out faster and need to be flattened more often. We recommend flattening them at the beginning of every sharpening session-it's a 15-second job in most cases. Flatten oilstones about every 10 sessions.
First, you shouldn't soak 3000 or over grit stones before use. Yet, you can splash some water if that's really necessary. Plus, bear in mind that you shouldn't use oil or any other type of lubricants or grease, but use only water for lubricating the whetstone.
In short, sharpening is used to restore a dull or damaged edge by removing metal, while honing is used to maintain and straighten the edge (which can bend over time). It's good practice to hone a knife often to maintain the edge and only sharpen it when it becomes dull.
A question that most people ask when they first start sharpening knives is should you push or pull when sharpening a knife. Most pros would agree that pulling the blade edge across the whetstone produces the best results.

How to use a Manual Knife Sharpener: Place the knife against the coarse side of the sharpener and swipe it across the surface around ten times. This initial step sets the foundation for a sharp edge. Afterwards, switch to the fine side of the sharpener and repeat the swiping motion ten times.
Depending on the material properties of the liquid, your knife edge will feel more or less slippery along the surface of the stone as you sharpen. Mineral oil is a little more viscus (or thicker) than water, so it has a slightly different feel while sharpening and, typically, it is preferred by most serious sharpeners.
It comes from the Old English term “hwettan” which means “to whet or sharpen.” Coincidentally, most whetstones do need some type of moisture for top performance. In all cases, this means water or oil. However, a majority of stones you'll find in stores or online–particularly for kitchen use–will be waterstones.
While plain water, windex ect. will work, Krud Kutter is the best lubricant to use for diamond sharpening stones.
To Sharpen = To Whet
Any stone used for sharpening was therefore called a "whetstone" or "whet stone". The terms "sharpening stone" or "honing stone" have largely replaced whetstone these days, but you will still hear it used occasionally.
Whetstones, Waterstones, & Sharpening Stones
Simply put, a whetstone is a stone used for sharpening tools and knives. The name derives from an antiquated word 'whet' meaning to sharpen.
Yes, a whetstone needs to be wet in order to be used. It should be soaked for at least 45 minutes, or per manufacturer instructions, Wetting the stone helps it last longer, while stones used dry tend to wear out faster.
