To me those CS knives looks like fancy bayonets. If you want a DAGGER to kill people, get a Sykes Fairbairn.
My suggestion would be to get a Fallkniven A1 or A2 if you want a big knife.
However a Fallkniven F1 or S1 might suit you better. They might not look combat enough but they really do the work.
If you are issued a bayonet I suggest using that for pry and destroy jobs and you keep the F1 or S1 for jobs where an edge is really important.
By the way, I would not buy a knife for 50 USD an think that I can trust it if I really need to. How useful is a knife if it is broken?
So forget the Cold Steel things and go for quality. Fallkniven F1, S1, (A1, A2, MC1), RC3, RC4, Bark River something. Any on these knives are really great for both military and civilian use. They look good both attached to a LBE or hanging from a belt while camping, although an MC1 might be a bit too much on a family trip
