I love MXG products and have always had a great experience, with quick shipping, and will continue to use them in the future. However, on this clip with the ZT0450, I think they could have made it just a bit longer (around a cm) to match what is needed for this particular knife. Since the knife is on the smaller side, they put the detent in a spot that makes it pretty easy to lock the blade closed just by putting a small amount of pressure on it in the wrong spot. ZT made up for this by placing the the lip of the bottom of the clip just so where even if your middle finger is there, the pressure from it is moved 5-10 millimeters down the knife and there are no issues with deployment (or much less so, still allowing the blade to fling open). Since the bottom of this clip ends a bit below ZT’s stock clip, this clip could have made up for it by being a bit longer, or at least having the option of a longer clip that would end in the same place as ZT’s stock clip. I’m still planning on using this beauty on another one of my knives but had to get another clip to replace this one on my ZT0450.
