Fun fact: I rarely used the Master Sword because when it gets "low on energy", I thought that indicated you were supposed to let it charge back up. So I ended up just letting it sit in my inventory for a while and then eventually when I got tired of it still being in the "damaged" state, I decided I'd just use it up and see what happens. It's a bit of a confusing mechanic. I don't remember the exact way the game tells you not to overuse it, but whatever it was I interpreted it to mean it consistently recharged.
