I rather enjoy knives that utilize multiple materials in the design. Such is the case with the Elishewitz Benchmade 690. This striking knife design uses 154CM blade steel (finished in a matte black), wood, carbon fiber and anodized blue titanium for the liners. A very classy and well made knife, the 690 deploys easily with a very smooth manual action. The carbon fiber bolster not only looks cool, it feels nice to! And the wood handle scales just add a fascinating touch of warmth. Adding a subtle-yet-classy detail to the knife are it's anodized blue titanium liners. Truly a unique and beautiful folding knife.
