The Macuahitl uses prismatic blades, in contrast with your everyday common blade (which is what I was referring to). I did a whole project on it, which is why I can say that physics means that the Macuahitl is much less likely to become unusuable due to chipping or fracturing than a normal blade that is likely to shatter, despite being made out of obsidian and wood.

Saying that aura will protect the blade is kinda a moot point- it takes more aura to protect a poorly constructed weapon from shattering than a good one. I just don't see the utility of having blades that shatter easily- if you want the frag effect, there are grenades,
