Shield?

I really like to see a shield SWEP, like the ones with CS 1.6, but for some reason was removed with Source. So could anyone give a whack at it, and give the end result to me?

And if you don’t know what I’m talking about, imagine it as like a riot shield, when you click your mouse, the shield would deploy over you and provide protection. Though, I don’t know about holding weapons at the same time.
