Designed by Dave Warren himself, the Tuya Envy V4 is a premium every day carry knife. It features a 3.5" S90V flat grind blade. The titanium handle includes purple haze fat carbon inlays. Deployment comes from the thumbstuds and the blade is secured with a frame lock. This knife has only been in my possession, and has not been carried or used to cut. It comes with all the original packaging material.
