My interest in knives are primarily the technical aspect with focus on functionality and mechanical properties as toughness and wear resistance. To achieve excellence in my knives I use the optimum materials for knives available today, and I have access to heat treatment practices unavailable for most knifemakers.

My background as a metallurgist gives me an understanding of materials beyond that of most. This is a great resource in most parts of knife making, especially in material selection and heat treatment. There is a vast number of steels on the marked, and those considered the best are in most cases not. To evaluate and choose materials you have to understand how the steel is affected by the composition and heat treatment.

Here is an interesting review about one of my Vanadis 4 E knives:
Zvi's steel composition chart is quite comprehensive, and list similar steels from different standards.
