as i am a bit of a noob in the way this all works (i can only create)
you need to choose which hands type you want and place the "v_hands"
into this directory:

C:\Program Files\Valve\Steam\SteamApps\YOUR USER NAME\counter-strike source\cstrike\materials\models\weapons\v_models\hands

hope you like them..

message me if you have any requests for custom weapon or hands skins...
