I personally think that using shovel as weapon would be a very good idea. There have been many times when instead of reloading or starting to shoot without aiming i would have just wanted to pick my shovel and smash enemy in to his head, that would be realistic. (no, shovel is much more dangerous and more effective then stock of the gun)
Even using my gun to reflect melee attacks would be a good idea too.
