I, personally, think stuff like this is cool.  I love the picture that SOG uses of a bullet being split by one of their old carbon steel knives.  As for this "test" of shooting the side of the knife, I am not too surprised by the results because another knife maker shot the side of one of his S7 knives and had a similar outcome.  Here's a picture of that:

 "Tests" like these to me are just fascinating (I suppose it's the engineer in me and my interest in material properties that causes this)!
