Yes, serrated knives can and should be sharpened, but much less frequently than straight-edged blades. Because the recessed teeth (gullets) do the actual slicing while the high points hit the board, the cutting edge experiences less friction and degrades very slowly. Sharpen them when they start tearing instead of slicing cleanly.
If you're constantly sawing through tough baguettes, you'll need to sharpen more often than the cook who only breaks out the serrated knife once a week to cut a bagel. But regardless, you won't need to sharpen a serrated knife nearly as often as a straight blade.
Serrated knives need different sharpeners than straight-edged blades. Most serrated knife sharpeners are rod-shaped, usually with a taper to accommodate different sized serrations. Sharpal 101N and 178N are featured with a tapered diamond rod for serrations.
Then I learned how the world's best chefs use theirs. Turns out, a bread knife is one of the most versatile tools in the kitchen. Gordon Ramsay uses it for pineapples and large fruits — the serrated blade glides through tough skin without crushing the soft flesh inside. Heston Blumenthal slices tomatoes with it.
However, when you want delicate, whisper-thin slices for your salad, serrated blades aren't going to cut it (figuratively); you'll want to use a razor-sharp straight-edge blade instead. Citrus and melons, on the other hand, have thick, sometimes coarse rinds that a serrated knife can carve straight through.
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.
Our favorite manual sharpener for serrated knives is the Chef'sChoice Pronto Diamond Hone for Santoku/15° Knives Model 463. Here are the Chef'sChoice user manual's directions for sharpening a serrated knife. (Consult your user manual if using a different brand of sharpener.)
Pull-through sharpeners are the most popular way to sharpen knives, and with good reason: They are quicker than whetstones and more precise than sharpening steels. However, they shed the most amount of metal, which weakens the durability of knives.
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.
First off, aluminum foil can't actually sharpen blades, at least not in the sense you're likely thinking of. Instead, it is more likely to hone them, meaning that it straightens the cutting edge slightly. By contrast, sharpening removes microscopic amounts of metal from the blade in order to renew the edge.
While serrated knives don't need constant maintenance, they should be sharpened when you notice tearing instead of clean cuts.
The Tumbler roller grinder is not suitable for serrations. The serrated heads of the bread knives are ground off and the surface of the diamond sharpening disc wheel can be damaged.
Trying to sharpen a serrated knife on a flat stone usually removes too much metal, flattening the teeth and shortening the life of the blade. That's why a specialized tool like the DMT Diafold is essential. Its tapered shape lets you match the original grind of each serration so you preserve the original edge geometry.
Select the slot that corresponds to the type of blade you're sharpening. For example, a slot labeled "fine" is typically used for sharpening kitchen knives without removing much of the blade, while a slot labeled "coarse" is used for serrated or heavily damaged blades.
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.
After sharpening, there may be tiny metal shavings or residue left on the blade. Always clean your knife with warm water and mild dish soap. Avoid harsh chemicals or abrasive scrubbers, as these can damage the blade and handle. Be sure to dry the knife immediately to prevent any rust from forming.
In many cultures, giving someone a knife or another sharp object is thought to symbolically cut or sever the bond between giver and receiver. The knife's sharp edge represents division, which can be interpreted as bringing misfortune to a friendship, romantic relationship, or family tie.
Yet despite all the talk about knives that goes on in both home and professional kitchens — and despite all the knives out there that are truly great to have — there are just three knives every kitchen ultimately needs: a chef's knife, a paring knife, and a bread knife.
A popular knife with Military and Tactical Law Enforcement Personnel, the SRK is the standard issue knife of the Navy SEALS for their BUDS - or Basic Underwater Demolition training - the SRK has proved its worth time and time again in the most demanding environments.
