lets you dig out shrapnel with the throwing knife (+ screwdriver) (#6259

)

# About the pull request

does what it says on the tin, found this to be mildly irritating that
you couldn't do it

# Explain why it's good for the game

mostly a convenience thing, lets marines eschew the normal bayonet boot
knife for a throwable if they prefer without having to carry the bayonet
in their webbing or rip the one off their gun every time.
