Neither blade is universally "better"; it depends strictly on the tasks you are performing. Straight blades are superior for everyday slicing, food prep, and precise push-cuts. Serrated blades function like a saw, excelling at tearing through tough, fibrous materials like rope, webbing, and heavy cardboard.
It depends: Serrated blades are better for sawing through the crust at the table; straight-edge blades are great for smooth trimming during prep. Pro tip: Keep both knife types on hand.
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.
Steak knives are serrated primarily to compensate for dulling and to make sawing through tough meat easier. The jagged teeth create concentrated pressure points that pierce hard crusts, while the recessed "valleys" are protected from scraping against hard ceramic plates, keeping the blade functional over time.
Serrated knives can be good for cutting through large cuts of meat, but serrated knives also typically have shorter blades than non serrated knives. However, this is not always the case. Typically, a serrated steak knife will not perform as well when slicing big cuts of meat compared to a non serrated steak knife.
Navy SEALs do not have a single standard-issue knife, but rather carry a mix of specific duty blades, hard-use survival tools, and custom-chosen personal knives.
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.
Three foundational knives handle 90% of culinary tasks: a Chef's Knife, a Paring Knife, and a Serrated Bread Knife. Together, this trio covers everything from heavy chopping to delicate peeling.
The best purpose of a serrated knife is for harder materials that require good bite in order to slice through. However, on softer materials, serrations may catch too easily and end up unwinding or unraveling the material rather than actually cutting it.
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 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:
Neither is universally "better"; it depends on how you like your steak and your maintenance habits.
What knife does a chef use most? The chef's knife is the most-used knife in both home and professional kitchens. It's an all-purpose kitchen hero that can prep virtually any ingredient and handle most kitchen tasks, making it an essential tool in kitchens across the world.
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.
Yes, you can sharpen serrated knives, but standard flat sharpeners will ruin the scalloped edge. You need to sharpen each "tooth" individually using specialized tools like a tapered diamond rod, a ceramic rod, or sandpaper.
A knife with a smooth, continuous blade is commonly called a straight-edge or plain edge knife. Rather than "sawing" through food, these knives use a clean push-cut motion.
Yes, you can use WD-40 as a lubricant on oil-based sharpening stones, but it is not the best option. Because WD-40 is very thin, it fails to effectively float away metal shavings (swarf), which can clog your stone.
Professional sharpening of serrated blades is possible but often costly and not always worth it. For this reason, experts typically recommend replacing a serrated knife when its performance noticeably declines – roughly every five to ten years for a frequently used bread knife.
Identify the beveled side
Most serrated knives are chisel ground, one side is beveled, while the back is flat. You'll sharpen only the beveled side with the Diafold.
Gordon Ramsay relies on a few core, heavy-hitting brands in his kitchens. His absolute top recommendation and daily go-to for an all-purpose knife is the German-forged Wüsthof Classic 8-Inch Chef's Knife. For full sets, he is a major advocate for the HexClad Japanese Damascus Steel line and frequently uses the Zwilling Four Star series by Henckels.
Best Chef Knives Overview
America’s Test Kitchen (ATK) named the Victorinox Swiss Army Fibrox Pro 8" Chef's Knife their longtime top pick, praising it for its lightweight design, razor-sharp edge, and comfortable, non-slip handle. At roughly $40, it consistently outperforms much more expensive knives.
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.
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.
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.
