It wouldn't work back home, because the rules are rather simple, but here belief seems to be the driving force of what actually happens. So if I added a thin layer to the sword, extending the width of the blade but making it more and more narrow, it might work. A monomolecular blade edge.<br/><br/>Though there should be a way to make a change and have it stay for a while after I stop concentrating. Something to do later."
