I do. I keep my sheers on my duty belt at my employer that doesn't permit EMT pants, when I work shifts in a city. My scissors holser is horizontal, and
also allows me to to hold a pen, multi-tool,
I also keep other stuff on it (radio holster, glove pouch, leather glovers, flashlight case), but that is just for when I work night shifts in an urban environments.
Plus my new job allows me to wear EMT pats, which allow me to keep the duty belt in my bag, and keep most of the supplies in my cargo pockets.
I also keep a set of sheers on the back of my FF helmet held in by a rubber band.
