Using a traditional whetstone (water stone) dry is not recommended. It drastically increases friction, leading to heat buildup that can ruin a blade's temper, and causes the stone to quickly clog with metal filings, rendering it ineffective.
Whether your sharpening stone needs to be wet depends on the type of stone you are using. The liquid acts as a lubricant to prevent friction and floats away metal shavings (swarf) so the stone doesn’t clog.
Most water stones need to soak in water for 10 to 20 minutes. You will know the stone is fully saturated when air bubbles completely stop rising to the surface. Keep in mind that fine-grit stones and certain premium brands have different requirements.
So leaving your stone in water might feel like a handy timesaver. However, leaving a stone in water for too long can damage them. It can make them really soft. So when you do eventually use them, you might damage the stone.
Here are the most common mistakes and proven ways to avoid them:
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.
In the high-end folding knife community, the original "Holy Trinity" refers to three legendary American makers who pioneered the modern premium tactical folder. Together, their designs set the gold standard for durability and precision.
Gordon Ramsay primarily uses a traditional honing steel (or sharpening rod) to maintain knife edges before use, emphasizing safety and consistent 45° angles. While he often uses professional whetstones for deep sharpening, modern demonstrations (and fan-used products) have shown the Tumbler Rolling Sharpener to be highly effective for achieving a razor-sharp edge on his knives.
When using a whetstone, you should use both pushing and pulling strokes for the most effective sharpening session.
Diamond stones can be used without any lubrication, but it's generally recommended to use either water (make sure to clean and dry it afterwards), a light machine oil or WD40.
Cutting boards made of glass, granite, ceramic, or your dinner plate may look stylish or convenient, but they are the fastest way to destroy a knife's edge. These surfaces are harder than your knife's steel. So every time your blade contacts them, it suffers microscopic edge deformation, chipping, or even rolling.
Choosing the Best Grit for Sharpening Knives
For most home cooks, a 1000-grit stone is the best option to get started. Follow up with a 4000 or 6000 grit stone to polish the edge. An 8000 grit is very effective for those who want an exceptionally refined mirror finish.
I Googled "How to use a whetstone", and the results were evenly split on whether to wet the whetstone (with water or oil) or keep it dry. Proponents of wetting say it helps lubricate and get the knives sharp quickly. Those against wetting say it traps metal particles in the water/oil, causing a ragged edge.
If you are just stropping and finishing a regular edge, yes it's totally fine I wouldn't waste money on a mid step. If you are thinning / polishing or working on a wide bevel you still can do it it's just going to take longer. A 3k between isn't a bad idea. You can, but every time you do God kills a kitten.
Soak the whetstone: Soak your coarse grit whetstone for 15 to 20 minutes. Soak your fine grit whetstone for 5 minutes. 3. Remove the whetstone and set on a towel: After soaking, place your whetstone in the center of a kitchen towel.
Too much pressure on one side of the blade might result in dents and uneven sharpening. In contrast, being overly light-handed may not produce the desired effects. Remember that mild and continuous pressure, as well as keeping a consistent angle, are key.
We usually leave this job to our partners), we suggest getting combination whetstone, something between 1000 and 6000 grit. Like this King's combination whetstone. These two stones and an inexpensive flattener will carry you a very long way. Add other stones or stropping supplies in the future as you learn.
3-Finger Test
Lightly place the knife edge on your fingers (sideways, not pointing down) and gently pull. A sharp blade will feel very "grabby" and not slip easily over your skin.
Gordon Ramsay was diagnosed with basal cell carcinoma, the most common form of skin cancer. He underwent successful surgery to have the cancerous cells removed from his jawline and used the opportunity to share photos of his stitches and a public service announcement encouraging fans to wear sunscreen.
Sharpening steels, stones and whetstones are great for home chefs who only occasionally sharpen their blades, and butchers who sharpen one or two knives regularly. But, if you're a commercial butcher who uses multiple knives on a regular basis, an electric knife sharpener is often best for the job.

Cleaning and Storing Your Stones
Always rinse your stones after use and allow them to completely dry. Do not use soaps with them or put them in the dishwasher. Don't wrap them in towels or store them in places without airflow. Residual moisture can make them mold.
Whetstones, especially natural ones, are extremely sensitive to moisture and temperature changes. The simplest daily habits can prevent irreversible damage: Dry completely after each use — wipe away moisture and let it air dry fully. Avoid direct sunlight — rapid drying causes cracks.
Here are a few common tools:
