It is veneer so not much you can do for repair. I bought a used board on ebay that had damage like that on all four corners. I bought brass corner peices on Amazon. Just make sure you buy the ones for the thickness of your board. My board was 3/4" thick so it was alittle difficult to find one for that as most are made for 1/2" thick boards such as yours.
I droped my chess board and one of the corners broke as you can see from the picture. Is it possible to restore it somehow, and is it worth it taking it to a carpenter to get it repaired?
