I suspect that the wood was not in equilibrium with the environment that the cutting board was being used in. Change in moisture can cause this type of wood movement.

Maybe they used it on top of that stove when it was still too warm or making a slight amount of steam.

Did you oil both sides before you gave it to them? If so, perhaps they washed it enough with soap and used it enough to deplete the oils on the top, and the top dried out, while the bottom did not lose oil.

There’s no standard or good way of unwarping a board, unless it’s a temporary warp to start with. How about putting feet on the concave side and making them a new board using equalized wood ?

A friend f mine brought an end grain board to me recently that was at least this bad. He wanted me to “fix” it! I simply laid it on my work bench for 2 weeks and it pretty much flattened out! He could not believe I did nothing to it and I don’t think he will be storing it over his sink anymore! It had been made to fit that sink and even though the guy that made it warned him, he did not properly care for it! It was pretty much wet all the time! Wish I had taken pics but, I didn’t think of that at the time! It had mineral oil and bees wax on it or so he said so it would have messed up a lot of sandpaper!!!!

I think someone left it standing in the sink over night on its edge with water still in the basin.

I had one do that. I think it was because the user washed it, then laid it flat on his counter. The moisture was able to evaporate from the top, but not the bottom. I suggested he stand it on edge until it had completely dried (overnight) and the problem went away. HTH

They probably ran it through the dishwasher a number of times…...

My wife left ours set in a puddle of water over night. Next morning, I had an end grain bowl. Put it in the oven on the lowest setting (around 170 degrees) and it flattened itself out after several hours.
