A sharp blade is the most important part of any knife. You may have heard about Obsidian blades being the sharpest material in the world, but the truth is, they’re not ideal for kitchen knives due to their brittle nature. A professional kitchen knife with this blade can’t take on large or oddly shaped foods and can snap into two.
Be it chefs knives, boning knives, paring knives, steak knives, fillet knives, or even top-of-the-line Santoku knives, using a knife with materials like stainless steel, German steel, Damascus steel, Japanese steel, and high carbon stainless steel, will never disappoint you – And, here’s everything you need to know about them.
In this blog, I’ll be walking you through the best Dalstrong knives according to your preference, the facts to consider before making your purchase, and how to keep your knives sharp.
1. What Is An Obsidian Blade?
Obsidian is essentially volcanic glass. The material is formed when the magma is squeezed and pushed down against the Earth’s surface. When cooled down rapidly, you get Obsidian. This material has a long history of being used in ancient times to make arrows, Samurai swords, and scalpels and was the sharpest knife in the world for the same reasons. While this is the sharpest material to work with, it’s not feasible to make a professional kitchen knife.
Kitchen knives undergo a knife test to check their sharpness and compatibility with knife sharpeners, and Obsidian blades crack and break during this process due to their thin, paper-like width. Here’s a quick summary of the qualities that the sharpest knife in your kitchen arsenal should have.
Some factors to consider include hollow edges on a sharp blade along with an ergonomic handle, pakkawood handle, or a stainless steel handle that is comfortable to hold and that passes the knife test.
Most important of all, a knife is sharp when it passes the paper or tomato test to check its sharpness. The blade material used on professional chef knives also needs to be compatible with kitchen sharpeners.
Obsidian’s biggest disadvantage is that it can cause jagged cuts that require invasive medical attention – This is also why they’re avoided in restaurants by chefs and by home cooks, too. Today, Obsidian blades are only used by surgeons when they need to work with state-of-the-art scalpels and other medical equipment.
These knives can cause serious injury when used with large or round foods that are challenging to cut with a serrated knife or a utility knife, too. However, many blade materials are stronger, more durable, and ten folds efficient and versatile than Obsidian. Let’s talk about that a little bit more.
2. Different Blade Materials Used For Kitchen Knives
Serbian Chef's Knife 8" | Shogun Series | Dalstrong
Stainless steel is by far, the most popular choice of knife material, and there are plenty of choices there too – Such as German ThyssenKrupp, Japanese, American, and highcarbon stainless steel. This is for a variety of reasons. They’re rust, corrosion, and stain-resistant, which instantly increases their durability. They’re low in maintenance, clean significantly more easily than other knife materials, and are dishwasher-friendly, too.
But, you can handwash your kitchen knife with a metal scrubber, too. And, don’t fret, they won’t take on any damage. In my opinion, the most impressive part about stainless steel knives is their ability to not cold onto strong fragrances of spices, tea, coffee, and other seasonings and sauces. This makes your favorite knife sets sanitary and clean to use.
There are multiple factors to consider when choosing a sharp knife, but stainless steel knives lasting for generations on end make the process all that easier. This material is an excellent conductor of heat too, so you don’t have to worry about oils and other liquids latching onto it. These knives usually have a wood handle attached to them.
German stainless steel, better known as German ThyssenKrupp steel, is great for a variety of reasons, including sustainability. German steel is famous for its wear-resistant, ultra-sharp, precision-forged qualities.
If you’re particular about achieving uniform and precise cuts on meats and veggies, this material was designed for you. Not only is it long-lasting and durable, but steelmakers also produce this material by using significantly less energy in the manufacturing process which then reduces emissions of greenhouse gas.
German steel is also less expensive than other materials while not compromising on quality, precision, and durability. The raw materials used when producing German steel are also of the highest quality which undoubtedly gives you a sharp knife with a sharp blade. These knives are equipped with an ergonomic handle made of stainless steel or wood.
Damascus steel is produced by using sheets of steel and iron and mixing it with charcoal in a no-oxygen environment. This allows is reduced and preserved steadily for top-notch cast Damascus steel. The eloquent wavy pattern on a knife is formed by mixing Wootz steel and maintaining it at a consistent temperature.
Damascus steel is known for its sturdiness, precision, and dexterity. These knives have a wood handle with rivets to keep the body of the knife super strong. This is ‘precisely’ why it’s slightly on the expensive side, but is a great investment, nonetheless. The blade is so incredibly robust that it encourages and maintains a safe kitchen environment with little to no mishaps – Just remember to sharpen your knives occasionally.

Japanese Steel Or High-Carbon Steel
Japanese knives like Santoku knives are the epitome of function-meeting form, thanks to the carbon content in the material. If cared for well, it can be the sharpest knife in your knife set with robust, resilient, and sturdy blades – Perfect to chop up some ginger or minced garlic.
Japanese knives need to be patted dry with a paper towel after each use. Oiling the blade will also give you precise cuts as there is less dragging this way. Maintaining them will also keep them free of rust and corrosion.
Knives with this material are hardened at 56+ Rockwell and are perfect for home cooks who want to expand their skills. This steel has less chromium present, so it can be sharp, but also a tad prone to rust and corrosion. So, just make sure you pat them dry after washing. These knives have an elegant pakkawood handle for an ergonomic feel. If you need more information about Japanese steel and knives, you may read more here.
