Pugio grips - why so thin?

[Poftim]

So far there have been two propositions:
1) The pugio grip was covered in organic material to make it like a more modern knife, the reason being that a pugio can't be held firmly in the hand because the grip is so thin and therefore is not ergonomic.
2) The pugio could be a throwing knife because it doesn't have a simple, straight grip, and has a concave aspect.

Are there any source texts, representational evidence, or archaeological finds supporting these notions?

I wholeheartedly apologise for saying you were clutching at straws earlier.

Robert said #1 has been clubbed to death, but in my opinion it doesn't hurt to try. However, if you all don't feel its correct anyways, no hard feelings here, I'll be trying it on my own anyhow.

As far as #2 goes, I think it should be given a shot. I don't know why you'd throw your weapon away, but who knows what those crazy Romans were thinking?

Discussion for #1 looks like this:


Anything else you all can think of that we should investigate about the Pugio? Maybe it was used to play Mumbly Peg.
