But you can use a scissor as a knife in most cases by holding the metal and sawing with it as you would a knife
You and I must have very different ideas of what level of sharpness is necessary for a piece of metal to be considered a knife. Yes, I can do that with my EMT shears; no, I don't think that's anywhere near as good as I want a knife blade to be.
Then again, I'm a bit obsessive about sharpening/stropping and using a high carbon content steel even though it comes with higher maintance requirements. As between a sawed off walmart steak knife and a shear blade, there's probably not that much difference.
