I have actually handled this flip folder. I have seen the evolution of several of David's prototypes for this knife - as each detail is improved. It is now really nice - the best of all the flippers that I have tried. There are many details that make it feel and work better than a factory made flipper and most custom versions that I have handled. The flip action is just right - smooth, fast and crisp. The shape and size of the blade and the handle feel perfect to me. The blade steel and treatment are also excellent.
I look forward to seeing models with the scales dressed up a bit with different patterns, carbon fiber, Damascus steel and other decorative materials.
