I always see that you should not sharpen mower blades "razor" sharp because they will dull quickly and are more susceptible to nicks.
I believe mower blades do not come really sharp because of liability reasons. Can you imagine the amount of people that would cut their hands changing blades if blades were actually sharp from the factory?
I sharpen mine to a fairly sharp edge and wear cut resistant gloves to install them.
Now hear me out, the sharp blades, if they do dull quickly, will reach an equilibrium where they will reach a close equivalent to a blade sharpened to a dull edge.
Now I will say a highly sharpened blade will nick easier in some cases, however this is not always the case in my experience because I have nicked plenty of blades shaprened to a dull edge.
I bring this up because I put a new unsharpened set on last night because I had hit a piece of metal by the road and really nicked one, and I did not have time to sharpen the new ones. Well I noticed they were tearing the grass, and the cut was just not as good as when I use a highly sharpened blade.
Just Sayin.....
