The secret of steel "ageing": how time changes the blades of knives and razors

The term 'aging' in the context of metalworking is usually associated with the natural or controlled microstructural changes that occur after the quenching/ tempering process. In the case of knives and razors, this phenomenon can have a significant effect on the behaviour of the blade, its cutting properties and its service life. In this article, we will discuss what steel ageing is, how it occurs and why it is of particular interest to vintage [...]

Knife steel carbide size: why does it matter and how to choose the right steel?

What are carbides in knife steel? Carbides are hard microparticles that are formed when carbon bonds with other elements in the alloy, such as chromium, vanadium, tungsten or molybdenum, during the hardening process. These particles are much harder than the steel matrix itself and have a strong influence on the cutting properties: the more carbides there are and the harder and more evenly distributed they are, the longer the blade [...]
