Just use them until they wear out, then put on new ones. Pay attention to the bolts, they wear out too.

The top, trailing edge of the lift fold and the leading cutting edge slowly erode away.

Unless you are close cutting regular cuts on fine grass (couch, Qld Blue etc) half worn blades are as good as new ones.

 

If you want to sharpen blades…

draw file them regularly

or

if using a powered grinder, don't make hot spots which will soften the metal, just use successive, quick wipes along the faced edge.

Sharpening usually causes balance problems.

I normally only sharpen full bar blades and then balance them, I don't bother with cheap rotary swing blades.

…also,

sand and weeds eat up blades a lot faster than lawns do,so try and keep a decent height on the grass leaves/blades, scalping lawns isn't worth it.

I'm not sure what others do here but I buy my blades in bulk for the Honda mowers like 50 pairs at a time they also come with bolts and washers.

And change them as required usually every 2 or 3 weeks In peak seasion it dosent take long to do but makes a huge difference mowing with sharp blades.

I sharpen mine with a bench grinder, it does make a difference,  replace them after about 3 sharpenings.   If you have a Honda you can buy the blades from boats.net for like half the price they sell them here, thats even with shipping.

Hi get yourself  Flap Grinding Discs,  you get a really superior edge and dont  overheating as bad compared to grinding discs.  there are many different types , get the finest you can  the bunning one below is a example.

I sharpen Blades from new put a edge on them the same angle as the lift flute.  they hold there edge very well as they wear.  and the extra edge does create extra throw.

 

I never resharpen them .  Swing back Blades are throwaways I only resharpen thick rideon bar blades but they need to be balanced .  BALANCER ====>>>  http://www.ebay.com....5oAAOSwcgNZCajB

 

Honda HRU216  blades are only $2 each including bolts and washes. $8 for a new set of 4

Some blades are a much harder steel than others too, the last lot I got were very poor in quality. Industrial Mowers were great for Victa and Honda, they would last much longer. But as Macka said for the cost it's not worth the worry.

as an aside…

On bar blades, 3/16" aluminium pop rivets are a better idea than factory type blade shear bolts.

Just as secure and seconds to replace. Hand riveter and spare pops in the ride on tool storage box (lunch box).

Last supply i get blades from dont have them anymore, these will do the job,  you could but a smaller pack and give them a try before buy 100 , thats what i would do. but looking into there reviews they look to be a outstanding ebayer with only 2 negatives and 12000 positives in 12 months'

 

I have got alot of stuff of these guys with no issues.  jonojohno20004  / http://www.chainsawspares.com.au

NOTE: make sure you get the right blades for you mower, HRU216 are different than HRU214, and get all high lift
