I've messed up plenty of mower blades over the years...
This one takes the prize...

Impressive really
Decades ago I bought a cheapie mower at Wally World. First few feet mowing the blade grabbed earth and bent. I took it off, braced it against the big tree and by hand pushed it back straight. Oops. Would have to be superman to do that. I took it back and got another one. Soft steel.
