I got 18 years from mine before nylon resin deck cracked. Engine was still strong as new...
An angle grinder should do just fine. I used to use a bench grinder and just follow the slope of the blade until it is sharp. No need to make it razor sharp or spend much time on it. I only sharpen once a year, but an angle grinder is so quick you could touch it up as often as you want/need.

I use one of the Dremel tool lawnmower blade sharpening attachments and it works good.
I'm really surprised no one has mentioned the need for balancing the blade is necessary after sharpening. An unbalanced blade could wreck your blade shaft bearings and or the crankshaft.
I got that too and will do that once the sharpening job is done.
This is what I was thinking as well.
To answer the op I usually sharpen once a year at the beginning of the season and make sure they are balanced.
Like others, our 4 acre yard has a lot of sand. Used to eat the lift at the back of the blades off annually.
The Bad Boy dealer talked me into fusion blades that have a hard surface treatment. Twice the price of regular blades but I’m on the third season and looks like they might make 4.
The cutting edge isn’t razor sharp but adequate for our country lawn that nobody sees.

If the blade isn't balanced, it can cause significant problems with one's mower. I've seen carburetor bolts work loose with grossly unbalanced blades and thread stripped and it's pretty difficult to tap new threads.
