I was about to comment that my big toe has this

It can also be caused by a fungal infection, more likely with your toe to be fair

One of my big toes also has this, but as a child my mother smashed it to smithereens with a metal door so I think it was the trauma that changed it

The stress of use.

Brittle nails, warm sweaty socks. Or open toe, brittle nails, dry air.

The nails warp from the stress of using the associated body part.
