Sandwich Damast/ Sandwich Patternweld (formerly Elite Gold)

As the name describes this is a pattern welded blade steel. The two outer slabs are 15N20 and 1.2842 to a 200 layer count. The center, as you can see, shows through on the knives (on the 5th picture this is clearest). The core material is a mixture of 3 steels: 15N20, 1.2842 and a cobalt steel to a layer count of 30-40 layers.

This steel is proven to be an outstanding blade steel. It holds an aggresive cutting edge. It takes a little longer to make sandwich damast so the price is different from from the random pattern weld nickle and carbon damasts I make. 

If you want a true performance steel for your knife you should certainly think about this sandwich damast as an option.
