Yes, cutting plastic does dull knives. While plastic is softer than steel, the continuous friction of a metal blade dragging across a synthetic, non-porous surface causes the microscopic edge of the knife to fold over and degrade more quickly over time.
But if you're using delicate Japanese knives, hard plastic can actually shorten their lifespan. The rigid surface can chip edges and dull your blades faster. Micro-grooves from chopping don't “self-heal” like wood does, which means bacteria can build up—and tiny bits of plastic could even end up in your food.
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.
Chefs use wooden spoons and spatulas to remove any risk of scratching pots and pans, and wooden boards don't blunt knives as fast as plastic cutting boards do. Both large professional kitchens and individual home cooks can appreciate wooden tools that help extend the lifespan of their other kitchenware.
The Hidden Dangers of Plastic and Rubber Cutting Boards
Knife Damage: Plastic and rubber cutting boards are notorious for dulling knives quickly. The hard surface can cause blades to chip and lose their sharpness, leading to more frequent sharpening or even replacement.
If your priority is knife maintenance, a well cared for wood chopping board will usually keep your knives sharper for 2 to 3 times longer than a hard plastic board used daily. In simple terms, wood is kinder to knife edges, while plastic is easier to sanitise quickly.
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.
The safest and healthiest cooking utensil materials are food-grade silicone, high-quality stainless steel, and natural hardwoods. These materials are chemically inert, heat-resistant, and free of toxic additives like BPA or microplastics.
Wooden Cutting Boards
Hinoki (Japanese cypress) stands out as the material of choice, deeply rooted in Japan's culinary heritage and having the lightweight cushioning, making for the perfect surface not just for the knife, but also for the Chef.
The healthiest cutting board materials are solid hardwood and stainless steel or titanium. Hardwoods naturally trap and deactivate bacteria, while metal surfaces are completely non-porous and shed no microplastics. Because each material performs differently, your ideal choice depends on your daily prep needs.
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.
Navy SEALs commonly use the Cold Steel SRK (Survival Rescue Knife) for training and the Ontario Mk3 Mod 0 for diving operations. While these are standard-issue, SEALs often choose personalized knives based on preference, such as those from Benchmade, SOG, or custom makers.
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.
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.
Chef Jacquelyn Lord, owner of The Dinner Belle in Chicago, breaks down the issue: “Knife blocks are less than ideal. Most people just cram them in the block, without thought for how the blades scraping on the wood can affect the sharpness.” Not only do blocks dull knives, but they also come with excess supplies.
The washlet can replace toilet paper completely, but many users opt to use both wash and paper in combination—although use of paper may be omitted for cleaning of the vulva. Some wipe before washing, some wash before wiping, some wash only, and some wipe only—each according to their preference.
In Japan, the "5-minute rule" (known as gofun mae kōdō, or "5-minute prior action") dictates that you should arrive and be completely ready 5 to 10 minutes before any scheduled meeting, appointment, or shift begins. Arriving exactly on time is often considered late.
In Japan, the most universally sacred colors are white (shiro) and red (aka or vermilion/orange-red). They frequently appear together to represent divinity and life.
Yes, you should get rid of black plastic kitchen utensils and cooking tools.
Avoid traditional non-stick pans with worn coatings or synthetic "forever chemicals" (PFAS), as well as unlined copper and reactive aluminum. Scratched or overheated pans release toxic fumes or leach heavy metals into your food.
If you're trying to avoid plastic, the safest bets are stainless steel, wood, bamboo, and food-grade silicone. Each has its strengths. Stainless steel is extremely durable and doesn't break down with heat, while wood and bamboo are gentle on cookware and naturally lightweight.
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.
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.
