I did like the Taoist idea I read a while back about a blade being sharp enough to sort of unmake something as it cuts through it, keeping its edge by not hitting any points of resistance that it didn't need to.
I even worked that into a key moment in my second book, from an antagonist character that had a habit of breaking swords a bit too much before that moment.
That seems to be how they're frequently depicted in media. And also lol "oh no my sword is too good at cutting! It's evil cutting!" playwrights lol.
