Japanese knives feature holes or dimples to prevent starchy or wet food from sticking to the blade. These indentations create pockets of air that break the surface tension and suction between the metal and the ingredient being chopped, allowing food to slide off smoothly rather than clinging to the side.
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.
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.
Knives have holes in their blades for several practical reasons depending on the type of knife. The most common purposes include preventing sticky foods from clinging to the steel, reducing overall weight and improving balance, allowing for a one-handed opening, or even functioning as a hanging loop.
Friction Reduction and Smoother Cuts
The most significant and frequently cited advantage is the reduction of friction and the facilitation of smoother cuts. The concave design dramatically minimizes the contact area between the blade and the food during cutting.
Many people probably know that Japanese kitchen knives and knives from Japan in general tend to be a certain benchmark of quality and sharpness. For example, a classic Japanese kitchen knife with a hardness of around 64 HRC made of white paper steel was carefully sharpened.
A real Damascus knife typically costs anywhere from $𝟖𝟎 to upwards of $𝟐,𝟎𝟎𝟎, heavily depending on how the steel is made, the level of craftsmanship, and the manufacturer.
Rule #1: It is important to use a knife adapted to what you want to do / food you want to prepare.

Rule #2: Don't drop your knife on the floor.
A "Texas Toothpick" most commonly refers to a traditional, slim folding pocket knife with a long, slender clip-point blade and curved handle. Alternatively, in Southern culinary circles, it refers to an appetizer of crispy, deep-fried jalapeño and onion strips.
According to folklore, giving a penny with a knife is a superstition meant to prevent the sharp blade from symbolically "cutting" or severing the relationship between the giver and the recipient.
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.
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.
The sharpest knife in the world is made from obsidian (volcanic glass). Because it fractures at the molecular level, its edge can be as thin as 3 nanometers. This makes it up to 500 times sharper than a standard surgical steel scalpel.
John Wick famously wields a signature series of high-end, out-the-front (OTF) automatic knives in his movies. The specific knives vary depending on the film, transitioning from production models by Microtech Knives in the first three movies to a highly exclusive custom blade in the fourth.
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.
The only knife federally banned across the U.S. is the ballistic knife (a spring-loaded knife that shoots its blade). All other restrictions—such as bans on switchblades, butterfly knives, and gravity knives—are determined entirely by individual state and local laws, which vary drastically.
In trucking culture, the phrase "trucker toothpicks" refers to toothpicks soaked in powerful stimulants—historically liquid methamphetamine or potent chemicals—that drivers would chew on to stay awake during long, grueling cross-country hauls.
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.
Giving a knife as a gift is steeped in centuries of folklore. According to superstition, a gifted blade can "cut" the ties or relationship between the giver and the recipient. To bypass this, traditional etiquette requires the recipient to "pay" for the knife with a coin.
In most places, including across the U.S., it is not illegal to carry a standard, non-locking Swiss Army Knife. Because they generally have small blades (under 3 inches) and require two hands to open, they are classified as legal pocket knives rather than prohibited weapons.
Never soak knives with wooden handles in water; prolonged exposure can damage the handle and rivets. Knives with plastic handles and without rivets can be soaked for longer periods without issue.
There is no single "number one" knife brand, as the title depends entirely on the knife's primary purpose. Leading experts and enthusiasts consistently recognize distinct industry leaders across different categories:
Cutco knives are made using stamped steel which means they're cheaper to produce. Although there's nothing wrong with stamped knives, they don't always hold their edge as long as forged knives. That means that you'll have to sharpen stamped knives sooner than forged knives.
Yes, Damascus steel can be made today, though modern techniques differ from the historical process.
