How often can safely sharpen a lawnmower blade?

I sharpen the edges of the sheet in my push mower every year, and I have done 4 times so far. I am afraid that after several sharp blade could one day weaken and perhaps break, while the motor turns and cause a serious accident, so how do you know when it's time to change the blade for a brand new?

Blades are cheap why risk? There is a balance sheet when you sharpen? Balance is important, an unbalanced blade can destroy engine bearings and dual cranks. You can buy balancer under $ 5. When my father had his mower shop is generally recommended that a new blade tip was reduced to about 1 / 2 to 3 / 4 inch. This was for security reasons, we have made more money selling new blades sharpened.
