Thanks to a similar crap pilot, I have a pristine looking polished prop from a 172 hanging in my house.
Same deal, BRAND new engine and prop, I think it had maybe 20 hours on it. Renter coming home from some trip and encountered some weather, decided to land at a little po-dunk airport with an extreme crosswind. Bounced, skipped, ran off the runway, across the parallel grass runway, and straight out into a field. At which point he ran STRAIGHT into one of those giant 10 foot tall bales of hay. Direct hit, engine first.
Engine/nosewheel ended up wedged under the fuselage, it was pretty yucky.
Well they sent the prop back to hartzel to get it bent back into shape, since he didn't hit anything hard it wasn't scratched or sliced as if it would be if he hit asphalt.
Anyway. Hartzel sent it back, red-tagged, irrepairable. Apparently he hit the hay bale at near full throttle (which baffles me why, but explains why we careened so far off the runway) and the prop was not only bent back under the nose, but it was bent chord-wise along the axis of rotation. Can't be fixed.
Long story short, it looks like a brand new prop, but it just rests in the corner of my stairwell landing looking pretty.
