The JYD is my favorite, hands down. Actually, the JYD is in my top three overall designs. I just love the way the handle feels and the shape of the blade. It's an excellent blade and I love carrying both my Large and Small. I haven't had a chance to carry my Lahars yet, but I will soon enough. I'm looking forward to start carrying them. The Turbulence is an excellent knife and out of all of them, this one flips the easiest and quickest for me. The handle shape and blade shape are fantastic and it rides beautifully in the pocket. I love the blade stop / thumbstuds and the texturing of the scales.
I'm really looking forward to the next model and I hope that Tim keeps the handles nice and smooth like in the Prototype. There something about the plain and simple look of the knife that really appeals to me. If the next one (Drone?) isn't smooth overall, I may have to pick up one of the smooth Turbulences from KnifeArt.
So now that I've gone all over the place, I'll come back to the beginning. The JYD is my favorite out of all of them.
