That covers pretty much anything one can hold sans complicated weapons that weren't present in his time period (railguns, probably guns in general, etc) - and even then, they can become bludgeons anyway.

Looking at Musashi's sheet, he has one big thing, and that's swords. All this ability does is allow him to improvise "swords" from "sword-like objects" and make them useful against Heroic Spirits. I think Bee's terminology is what's getting everything mucked up here, as it doesn't create a Noble Phantasm weapon, but something that can be used to fence against one using a Noble Phantasm weapon. In other words, it allows Musashi to swordfight with King Arthur.

This sums it up pretty well.
