Ah, heh, I didn't even check the images to be honest. Lever-operated crossbows would be a lot more common than crank-operated ones, that's true, and significantly cheaper as well. And you don't have to change the dirk if you don't want to, I just wanted to warn you that replacing the crystal hilt with one of a different material (presumably still a magically conductive metal, although organic materials could substitute these) would impact how low the level of skill required to use it would be. The average rune mage doesn't need to be able to control magical energy at all, whereas someone with a weapon like the dirk would need to be able to control and direct their energy-flow at will to be able to use it effectively.
