There is no doubt that EMT type scissors are handy as can be. I have several of them, and have just about stripped accident victims naked with them. They can cut all kinds of stuff, a former co-worker once managed to cut thru control cables on a light aircraft (VERY tough stuff) with his to extricate the injured pilot. Only thing that comes to mind you can't do well with them is clean your fingernails and make fuzz sticks (or other wood "whittling" kind of stuff. But I still carry my Leatherman on me all the time, while I leave the shears in my larger FAK...
