Replacing the Crowbar with the Stunstick
Switching the crowbar to use the stunbaton is as simple as opening your scripts/weapon_crowbar.txt. Inside, find these 2 lines:
"viewmodel" "models/weapons/v_crowbar.mdl" "playermodel" "models/weapons/w_crowbar.mdl"
And change to:
"viewmodel" "models/weapons/v_stunbaton.mdl" "playermodel" "models/weapons/w_stunbaton.mdl"

Third-party Commentary: One of the more useless article i've ever seen.
