Location of HL2 Crowbarswep script?

I am currently working on a weapon based off the HL2 crowbar, but I am unable to find it. Can anyone please give me any leads?

All HL2 weapons are coded in C++, you won’t find code for them in GMod installation because it’s compiled into a .dll file.

EDIT: Well, if you really want it, there: https://github.com/ValveSoftware/source-sdk-2013/blob/master/mp/src/game/shared/sdk/weapon_crowbar.cpp
