Knives typically lose their edge quickly due to hard cutting surfaces, improper storage, the dishwasher, or poor cutting techniques that bend the microscopic edge of the blade.
Never cut on glass, ceramic or countertops. Those surfaces are harder than a knife's edge and will quickly dull the blade. It's what you cut on that dulls knives, not what you're cutting.
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.
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.
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.
There is no magic knife that never dulls, but self-sharpening knife systems offer the next best thing. Instead of sharpening your own knives or paying for a professional service, these systems have a sharpening mechanism built directly into the storage block to restore the blade's edge in seconds.
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.
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.
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.
Illegal knives: All knives with automatic-opening (switchblades), push daggers, gravity knives, disguised knives (belt-buckle knife, sword cane, etc.), knives with two-parted handles (butterfly knives), knives with ready access by the wearer (neck or belt knives, boot knives, etc.) are illegal to own or possess.
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.
The Tomato Test
Cutting a tomato is the ultimate test of a knife's sharpness. Their thin slick skin, rounded surfaces and delicate insides are hard to slice with finesse using anything but the sharpest of edges. A sharp knife will glide through the skin without crushing, bruising, or destroying the insides.
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.
To determine if a knife is of good quality, check for a full tang (where the metal extends all the way through the handle), high-carbon steel for durability, and a balanced, comfortable grip with no gaps or rough edges.
No, aluminum foil cannot truly sharpen a knife. Aluminum is much softer than steel, so it lacks the abrasive material needed to shave off metal and reshape the edge.
Achieving a razor-sharp, mirror-finished edge comes down to two main principles: maintaining a strictly consistent sharpening angle and fully removing the burr (the curled-over metal at the apex of the blade).
For most kitchens, you only need three foundational knives to handle 95% of prep work: a Chef's Knife, a Paring Knife, and a Serrated (Bread) Knife. These three powerhouses can tackle anything from dicing onions and slicing crusty bread to peeling fruits and carving small meats.
A: Yes, the Benchmade Bugout is generally legal to carry in California because it is a manual folding knife, not a switchblade or fixed blade. California law allows folding knives to be carried openly or concealed, including clipped inside a pocket, as long as they do not automatically open by a button or spring.
Stiletto knives are often restricted or illegal because their needle-like, thrusting design makes them uniquely suited for deep penetration, while their quick-release mechanisms (like push-buttons) historically associated them with 1950s gang violence and cinema, prompting widespread legislative bans.
Except for plastic or round bladed butter knives. Any sharp objects in checked bags should be sheathed or securely wrapped to prevent injury to baggage handlers and inspectors. The final decision rests with the TSA officer on whether an item is allowed through the checkpoint.
There is no single "best" steel for knives because the ideal choice depends on your primary need: edge retention, corrosion resistance, or toughness. Today, a few exceptional steels stand out as the top performers in different categories:
Yes, soldiers still carry knives. While rarely used for combat, they serve as essential survival tools for cutting paracord, opening ration packs, and field repairs.
Whether you're a professional chef or a passionate home cook, keeping your kitchen knives clean and sanitized is essential for both food safety and knife longevity. Proper cleaning not only removes food residues and bacteria but also protects the blade's integrity and prevents corrosion.
Choose a high-quality knife oil specifically designed for pocket knives. Avoid using household oils like WD-40, as they can attract and stick more dirt in your pivot, ultimately leading to more significant problems.
It will chip, dull, and corrode your knives, including a high probability of causing pitting corrosion—a particularly nasty, localized form of corrosion.
