Masamune and Muramasa? I've been thinking about that. Something about it sounds good to me, but I'm not sure what. I thought it had to do with the swords and the sorcery that created them. I wondered, if it were possible, what steps would one take to imbue an object with magical qualities? Real magical qualities. It think it would be in the details (not some fancy incantation), the rub of a quiet thumb, skin subtle, something just slightly below or outside normal perception, so as to "sneak into" the object, to create a presence felt but not known, an appeal without appealing. No one can do this, of course. Or so they say... The magic in the story led me down this path, for instance, are there other accounts. How many people were there? Could there have a been a multitude of witnesses, each with their own interpretation? Some swearing they saw... "...magic, I tell you it was magic. Muramasa's sword would cut, Masamune's would heal.And it repelled any leaf heedlessly charging at it, repelled it, I'm telling you, a miracle..."
You know that one of the ways to judge if a chisel is sharp is simply to look at its edge. If you can see the edge, the chisel's not sharp. Which means if you can't see it, it is sharp. Interesting, don't you think? The absence of evidence - you can't see it - provides the evidence - it is sharp.Let's consider the circumstances: Of all the ways to test for sharpness, why drop your sword in a brook? Which of them suggested this test? Why? Was it, possibly, the monk? Did he know what would happen?
