When reading this all I could think about was Glamdring and the ancient's insistence on the soul of a warrior being embedded somehow in their weapons.
I've always had a deep love of circus skills including Staff and Sword play, and remapping my "physio-spatial" model is second nature. The eerie part is when you can actually feel it happening, it feels like the sword/tool forces it's way into your consideration. I can only imagine what it must have been like for the blades and tools of old, with all their might and "magic"!!
