Chosen Solution

I have a small Honda 3.2HP push mower and its 10 years old and the blades have seen better days, how could I sharpen it the easiest possible way?

you could use a old fashion sharpening block, like the ones you sharpen a knife with and grind it down to a angle so you get that perfect edge, it may take some elbow grease but those blocks work great. I’ve heard people using sandpaper but I wouldn’t suggest it.
