Better cutting blades

[GT012]

I'm looking for better suction/mulcher blade for a Honda 21" commercial mower.
The standard two blades work okay, but they wear so fast, like within a 4 days, than my Toro blades and don't pull up all the debris on the grass. I can run over a left blade and watch it come out on the otherside. I do both bag and mulch so would like a blade that can do both if possible. I would use my Toro but they are sure high mantenence than my Hondas. So if anyone can suggest some blades that don't wear as fast and can such up anything I put it thru that would be great..
Thanks

They wear so fast? Like you have to sharpen them every a 4 days? or they are shot after 4 days? Sharpening daily is a normal thing to get used to
