5. Frequently Asked Questions. What is the sharpest knife material? Knives with an Obsidian blade are considered the sharpest in the world, but this material is not fit for making kitchen knives as they're extremely coarse and brittle.
Vanadium carbides are among the hardest that form in steel, and chromium carbides are in between iron carbide and vanadium carbide. Steels with very high vanadium content like Vanadis 8, CPM-10V, K390, CPM-15V, etc. have extremely high edge retention.
Steel with a high content of carbon (C > 0.8%) remains sharp for a longer period of time, its sharpening is easier, but the blade develops a patina because there is no addition of chromium (Cr).

A 17 to 20 degree angle covers most kitchen knives, pocket knives, and outdoor knives. Some knives (typically Japanese manufacturers) will sharpen their knives to roughly 17 degrees. Most western knives are roughly 20 degrees. In fact, a 20 degrees angle is often considered the best sharing point for most knives.
However, Damascus steel knives are much stronger than stainless steel ones and maintain their sharp edge for lengthier periods. However, these blades require tons more maintenance and are susceptible to rust if not correctly cared for.
Obsidian is a naturally occurring volcanic glass. It is a hard wearing material and can cut through materials such as marble and bone. It is shown here with a piece of skull trephined with an obsidian knife. The hole produced is 19 mm in diameter.
