High-end kitchen knives, especially those used by professional chefs, typically use high-carbon steel. It makes the knives wear-resistant and helps them hold a sharp edge longer than stainless steel. High-carbon knives also make more intricate cooking techniques like precision slicing, carving, dicing, and chopping vegetables and proteins much easier.
Aogami super (or Blue Super) is often credited as the highest quality high-carbon steel in Japan. It’s extremely hard and typically used for premium all-purpose chef knives, such as Gyuto and Santoku. Having said that, there are a number of different high-carbon alloys to choose from, each offering you different advantages depending on the style and level of your cooking.
The hardness of high-carbon steel does come with a trade-off. It makes the knife more brittle and prone to chipping if used incorrectly. Traditional single-bevel Japanese knives can sometimes require a bit of practice to get used to before you perfect them.
The low chromium content in high-carbon steel chef knives also makes them more susceptible to rust and corrosion. This is why it’s important to wipe off excess moisture from your knife immediately after use.
It’s not uncommon to see knives being passed down across generations in Japan. With the right care, your knife can last you a long time.
It is recommended to hand-wash your knife with warm water and wipe it clean with a soft cloth. Wipe off moisture immediately after use and store it in a dry environment. This will help prevent rust and corrosion, as will regularly applying Tsubaki Camellia Oil. Never place your high-carbon steel knife in a dishwasher.
Use a whetstone to regularly sharpen your knife. This will give you much better results than if you used an electric sharpener or a honing rod.
