The heat treatment process is arguably one of the most key steps in the process of making a tough, reliable knife. Without proper heat treating, the knife would probably fail at some point during its intended use and edge retention will suffer. Possible setbacks in using such a knife would include brittleness and inability to withstand abrasion and physical impacts, resist deformation due to thermal shock, withstand compression forces or even the inability to retain a usable edge.
What is Heat Treating?
Although the phrase heat treatment may suggest that this process involves the simple process of heating the knife’s blade, the cooling aspect is just as important in the process. In fact, this may be the most important aspect in the entire craft. The way you cool the blade after heating it will determine whether you will get the desired properties in the blade, negative properties, or none at all. Obviously, the temperature to which the steel blade is heated will also be an important factor in process. Continue reading this post ➜
