There could be magnetic nails which focus on divining information using magnetic fields. Nails that point towards living EM fields, nails that point towards high concentrations of a chosen metal, nails that just point north. Maybe some more mystical ones that don't have anything electro-magnetic, but still point towards specific things when used.
Rusting nails could be used to destroy things through an infectious rusting corrosion. Including things that aren't necessarily oxidizing metals, it is magic after all. Drive a rusting nail into a crack in a cave wall and it starts collapsing that section of cave, hit a person and they take damage over time or suffer other debilitating conditions.
Maybe there could a form of nail magic that meshes with acupuncture, using thin and precise nails to hit and stimulate the vital parts of ones body, allowing nail-based healing and treatment. The effects would never be as fast or obvious as more standard magics, but still useful enough especially in their absence.
Perhaps we could also have wedging nails, made for cracking things open or apart. Much like magics that force a door open, these would be hammered in next to the doorknob to force a door to crack open.They would be a natural counter to any conventional nails pinning a door in place.
There could also be combinations of these nails and their effects, though balancing such a thing would be rather difficult and may ruin the spirit of having distinct separate elements.
What is your ruling, my nail obsessed compadre?
