The other main wearing part is the upturn of the blade which shoots the grass etc into catcher. That seems to affect cutting performance the most for me.
Yeah just install new blades when the up kick for the mulching action wears through toss em and install another set, because there usually is not enough left of the blade to sharpen. Then again, I don't have St. Augustine grass either. I like to cut my grass almost so short it is like scalping the lawn that way I hopefully won't have to mow again the whole season. Never works out that way but I keep trying anyway. The only bigger waste of time than having to mow would be to water and fertilize so I would have to mow again. Sometimes think about just getting some goats instead.
