For most knife sharpening, a 400-600 grit diamond stone is ideal for repairing or creating a new edge, while a 1000-1200 grit stone is best for general maintenance and sharpening. Use coarse (200-300 grit) for deep damage and fine (>1200 grit) for polishing.
For Professional-Quality Sharpness: For high-end knives or professional use, progress through the grits from coarse to fine, ending with an ultra-fine grit (6000-8000) to achieve a superior edge.
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.
Characteristics of coarse grit (200-1000)
As the grit increases towards 1000, the stones become less aggressive but still remove significant material. Coarse stones in the 400-800 grit range are versatile for general sharpening and maintenance, striking a balance between material removal and edge refinement.
Use a medium sharpening stone ranging from 600 to 1000 grit, followed by a fine sharpening stone ranging from 1000 to 3000 grit. Repeat the test until your knife will easily cut through the paper. Does your knife easily move through the paper?
Chefs primarily use whetstones to actually sharpen their knives. However, to maintain the edge during busy shifts and prevent the blade from going dull quickly, they regularly use a honing rod (often called a "steel").
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.
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.
When using a whetstone, you should use both pushing and pulling strokes for the most effective sharpening session.
If your knives are very dull or have nicks and chips, start with a coarse grit, such as 200 to 400, to remove the imperfections and reshape the edge. Once you have achieved the desired shape, move on to a medium grit, around 1000 to 3000, to refine the edge and remove any remaining scratches.
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.
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.
Bobby Flay most frequently uses Shun knives, specifically the Shun Classic Western Chef's Knife. He loves these Japanese-crafted blades for their lightweight balance and versatility. For smaller, all-around prep, he has also been known to reach for the Shun Classic Hollow-Ground Santoku.
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.
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.
Sharpening a knife on a whetstone typically takes 10 to 30 minutes for a standard kitchen knife. However, the exact time depends heavily on the knife's condition:
Here are the most common mistakes and proven ways to avoid them:
Rule #1: It is important to use a knife adapted to what you want to do / food you want to prepare. For example, you shouldn't use a bread knife to slice a roast or use the blade of a paring knife and use it as a screwdriver (don't laugh, we've all done it!) Rule #2: Don't drop your knife on the floor.
Pull-through sharpeners are not universally "bad," but they are generally discouraged for high-quality or expensive knives. They offer quick, convenient edge maintenance but are highly aggressive, removing excess metal and often leaving a fragile, jagged edge.
The best knife lubricant depends on your application: for food prep, use food-safe mineral or coconut oil; for folding knife pivots, use high-performance synthetics like KPL Knife Pivot Lube; and for low-mess storage, choose dry lubricants or waxes.
Yes, you should always wash a knife after sharpening. Sharpening actively removes steel from the blade, leaving behind microscopic metal shavings and stone grit. Washing prevents these particles from transferring into your food or causing the fresh edge to rust and corrode.
Navy SEALs rely on a few specific standard-issue fixed blades, but they largely carry mission-dependent gear. Standard-issue knives include the Ontario MK3 Mod 0 dive knife and the Cold Steel SRK. For everyday carry and field operations, operators frequently choose rugged folding knives from premium brands.
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.
If you have one chef's knife, one paring knife, and one bread knife, consider yourself equipped with thetop three knives every kitchen needs. Now it's time to find something good to cook!
We tend to grind to 13-16 degrees per side. If you match the existing edge angle and hold the knife against the stone to cut evenly across the edge grind, you will produce an edge with a similar angle.
