How to out custom hands in a swep?

[FalconPanch!]

Hello!, I´m new on this of lua scripting and i was wondering, how i add custom hands into a swep?. I already port/import CS:S knife (with a custom model that i found) with my own lua script to gmod but how do i chage the hands model?,if i decompile the bones of CS:S can i rig my custom hands model with them and then compile them again, or something like that? Sorry my english :)

To make your SWEP use the viewmodel hands, add this code:

SWEP.UseHands = true

it must also use a c model for its viewmodel:

SWEP.ViewModel = "models/weapons/c_smg1.mdl"
