The scalpel seems like one of the best weapons I’ve tried so far - I think I have it at rank 4 and it draws 25 blood per hit, which is fantastic if you like to cast Shadow Mist or other abilities often. I’ve completely stopped using stun weapons and even specced out of all bite perks I had (hunger mainly) because I stopped using it. I don’t know what to do with the Hacksaw though - extra blood drain per hit is very nice but having some more damage could also be useful.
