CS:GO skin changer feature

Dear Staff! 
I'm planning to buy a lifetime csgo, but want to ask about the skin changer.  Can I change the knife's model to a karambit or a bayo, or it just adds a pattern to the default one? Also, only real skin combos(like awp asiimov) or unique ones (ex: awp guardian)

Yes you can change the knife model and it fixes the animation too. Im not sure what you mean by unique skin combos, but you can get all the real ones that are possible in game.

Thanks for the fast response! Im surely buying this in december.
As uniques I ment that "not existing skin combos" like blue laminate on m4 or smth like this (just to make it clear)
