Groundhog, the piece of shrapnel that got me really was NOT very big. It was maybe 3 inches long and about an inch wide but it had impact! I've seen some pieces of shrapnel that looked to be size of a lawnmower blade and all sorts of jagged so I know exactly what you mean. The thing was that when I got hit, my arm just sort of flopped away from my body and then I felt two types of pain. One from the cutting and the other was a burning pain from the heat of the shrapnel. I will always remember that incident because until then, I had no idea what guys meant when they got hit with shrapnel about it "burning and hurting." Now I DO understand it but I had to learn about it the hard way.
