The fixed blade knives are from the Bone Collector series. The 15020 and 15030 folding Axis lock knives are gone, replaced by two other Axis lock knives with more traditional-shaped blades. Dymondwood is tough as nails and a good choice for handle material. It comes in many colors, but I notice that Benchmade is only using it in traditional wood colors. S30V is fine, but I think I would have preferred they stick with D2, as it is tougher than S30V and holds its edge just as long (or longer). Of course, it can also be harder to sharpen.
The two lockbacks are carry-over from the Bone Collector series: 15050 and 15055, with D2 blades. Same options on handle color, but the BC series used cocobolo for the wood. Looks exactly the same except for the Bone Collector logo.
