Yeah, no one I know uses them past early game and on the rare occasion they do, they never throw them because if they get lost it's much bigger loss than an arrow or bolt. So effectively it's a 2 hander with less damage than the sledge and no power attack.
Other Ideas: two dye slots for knuckles so they can be different colors. Also, if you have Wasteland Treasures 5, and you one shot a reinforced door, you don't get a knob. You have to strip away the reinforcement first, that's wack and should be changed.
