The buck is a classic , there are many factors. One is I dont like carrying that 110 in my pocket its just to heavy. so that makes it a sheath on the belt knife ,depending on what your job is that may or may not work for you. Maybe you already have 3 or 4 or 5 things on your belt. I have to carry a flashlight , radio , sog multitool , so the extra weight of the 110 is not welcome though I could manage it if I so choose. There are to many other options to consider though. My edc is a spyderco endura 4 , its light weight , strong , the edge holds up extremely well , it has a low profile in your pocket. The smaller fixed blades work well also , many you can just slide down in your pocket and no one would know. I would take the kabar over the buck if that were the only choices.
