I purchased the Medium Luzon knife from Cold Steel a few months ago, and since I've had it, I have used it--a lot. I will start with the look and feel of the knife. The grip feels great in the hand, and the knife overall is well balanced. I am not a huge fan of the clip as its not metal, but it holds on tight to my pants. I do often have issues with knives opening in my pocket, and I wish this knife's blade safety could be used to prevent the knife from opening instead of just locking the blade open. The blade-lock spring works fine and has enough pressure to keep the blade open, but if the blade is flicked open too hard, the spring gets jammed. I have to stick a key or flathead screwdriver between the grips and pry it open to get the spring lock to disengage. The blade, though, is amazingly sharp. I'm pretty rough on knives, and I have had zero issues with the blade dulling. It's just as sharp as the first day I've had it. I've used it for cutting up baitfish for catfishing to cutting up boxes for recycling. The knife is also lightweight for its size. I would definitely recommend this knife to anyone looking for an all around EDC knife.
