Why does everyone overthink lawn mower blade sharpening?

I see posts on here all the time where people spend 45 minutes with a dremel tool or a bench grinder trying to get a perfect razor edge on their mower blades. My grandpa showed me how to do it with a basic 10 inch flat file back in 2008, and it takes me maybe 10 minutes total for both blades on my old Toro. The trick is you don't want a sharp edge like a kitchen knife, you want a smooth, slightly dull edge that won't chip when it hits a rock. I see folks balance their blades with a special tool too, when you can just put the center hole on a screwdriver and see which side dips. Last spring I watched my neighbor file his blade for 30 minutes, put it back uneven, and then blamed the engine for the rough cut. He has done this three times now. Has anyone else noticed people wasting time on lawn equipment maintenance that really doesn't need to be that complicated?

Took me straight back to when my buddy tried to sharpen his blades with a bench grinder and ended up grinding one side down so thin it snapped off mid-lawn. Had to borrow my mower for the rest of the summer till he found a used set on Craigslist.

You're absolutely right that people overcomplicate this, but I wonder if it really matters that much in the long run. I mean, unless you're cutting golf greens or something, a few minutes either way probably doesn't make a huge difference to the average lawn. My husband spends maybe 15 minutes with a file and never checks balance at all, and his grass looks fine to me. The real issue is people like your neighbor who change the angle or take off too much metal on one side, then blame the mower. But honestly, obsessing over the perfect edge or spending money on special tools feels like a solution looking for a problem. Most of us just need the blades sharp enough to tear the grass cleanly, not surgical instruments.
