knife to first aid kit

this wont work, you can make a knife look like a first aid kit (dunno how it would swing) but it wouldnt be able to heal, and it would only show up on your screen.
there used to be a shoot anything out of your knife hack but itwas VIP onlyand im pretty sure its permanently patched.

You can definitely make it look like one. But it will have no effect at all.
Just like the time i tried to make mines into m93.
