How often do a need to sharpen my knife?
- You should sharpen your knife as soon as you notice that the knife blade is starting to become dull. How long it takes for this to happen depends on how much you use your knife. Normally it is enough to re-sharpen your knife a few times per year.
What is carbon steel?
Before the invention of stainless steel, all knives were made of carbon steel. Due to the lack of corrosion resistance compounds in the steel, carbon steel is very pure and is able to attain an incredibly clean and sharp edge. However, this also makes the steel much more sensitive to corrosion and rust. Therefore, it is very important to wipe a carbon steel blade clean and make sure it is dry as soon as possible after using and washing the knife. If small spots of rust appear on the blade, they can easily be removed with a cleaning sponge and some water.
Will the patina on my carbon steel knife come off if I wash my knife?
- The patina is a light surface treatment that is forced on the blade in order to protect it from corrosion. This is not a permanent treatment and can come off if washed intensely with abrasive sponges and detergents. However, the patina can come back naturally over time if the knife is used and maintained properly. Cutting acid rich foods, such as lemons and limes can increase the speed of this process.
The patina differs slightly between two of my carbon steel knives, is this normal?
- Yes, as the patina is a result of a special treatment that forces a fully natural reaction to occur on the blade surface, there will always be small differences in the patina. Also, if you use your knives each knife will develop it’s unique patina over time. We find this to be one of the great experiences of owning a carbon steel knife.
