re: Oops

More like "ouch"!

Certainly will have a stadium full of raised hands when asking if this ever happened to anyone else.

Can't really tell from the picture, but is that a chip missing or just crushed wood?

Whenever I get crushed fibers from a ding, I'll try to place a wet rag over the spot and use a clothes iron or other appropriately sized heat source to steam out the dent.
The idea is that the water will swell the fibers and (mostly) restore the original shape.

Depending on the position, I'd probably wad up a wet rag, set it on a plate and prop up the object with that corner buried in the rag to soak up the water for a few hours.

Then comes the heat, probably a heat gun in this situation. Just heat and repeat until things look better!

If this is a box, I'd also consider just cutting off the top x" amount to get past the ding if the water didn't work.
