make a knife weapon that when thrown at stuff like a wall/player would pull you towards them after pressing the trigger (the one on the top)or pull it back to you if pressing the other trigger (the one on the side(?))
there would also be a bleeding mechanic that when thrown at a players head and pulled out would do slow bleed damage until it did 1/4 of someone's health and cant be stacked
the knife could also be hit out of the way by a weapon making the thrower unable to grapple it to them or themself to it until they threw it again
