This is one chocolate beauty! and the second composite blade In my collection. Complete with chocolate icing!!! The Kershaw Tyrade 1850 Composite blade this is 2 high grade steels fused together to form a perfect knife. It has carbon fiber inlays and a thick liner lock you wouldn't believe it's built like a tank. With cm154 on top and cpmD2 on the bottom. It's a spring assited blade that pops out with authority and make the coolest swooshing sound when deployed. This is easily the coolest blade in my collection right now!
