Some twenty or more years ago, I acquired a ceramic-bladed folder from a major European cutlery manufacturer. At first, I was a little skeptical about blade durability. However, after using the knife on a couple deer and a wild hog, those concerns no longer plagued me. The one thing that I did learn about ceramic blades is that they are incredibly sharp and hold an edge almost forever.
A valid criticism of ceramic blades is that they aren’t nearly as tough as a steel blade. Drop one on a hard surface, or apply lateral stress, and you quickly have an understanding of the limitations of ceramic blade material. Any ceramic blade can break if subjected to abuse. And given the cost of most ceramic knives, hunters have not embraced the technology with great enthusiasm.
Despite the lack of lateral ductility, a ceramic blade does have several features that any hunter will appreciate. A ceramic blade will stay sharp much longer than a carbon or stainless steel blade. In addition, a ceramic blade cannot rust and is not affected by blood or digestive fluids. A ceramic blade is also extremely lightweight when compared to a similar steel blade.
