I wanna know, cause I wanna start production on all of 'em. I already know the buzzer blade gun, and scratch tube, and the super heater crossbow, but I've yet to find 1 for harpoon gun and harpoons, never even seen the harpoon gun even, just the harpoons in black desert city. I also don't remember if I've seen any prints for the arbalists at all, and I can't seem to find where I can make the damn saw blades for the buzzer blade slinger.
