Blender 3d For Weapons In Source Thread

How can I model weapons for source with blender, and animate them. I only know how to do props. I can't find anything. Can anyone help me? I know it's possible, somebody on youtube did it.

Edit: I've found a tutorial on the valve developer wiki, but how do I get the hands into blender to animate?
