I have a DPx HEST/F 2.0 Triple Black and its a beast of a knife. Feels like a tank in hand and has a very solid lock up and deployment. They're a great chunky knife that's very pocket friendly considering the overbuilt nature. Two criticisms I have: I'm not crazy about the Rotolock. Sometimes it engages when you don't want it to. I'm not in favor of most secondary safety locks, but if you have to have one, none are executed as well as RealSteel. Also I think the fit and finish on the knife is lagging behind the price tag. It's a $200 knife with a $100 knife construction quality. But, hey, they made it to use, not sit pretty in a safe somewhere.
