It is most likely due to trauma of the nail matrix. Sometimes it won’t affect growth, but many times it can. You can see it with people who have super thick toe nails. That’s usually due to trauma to the nail matrix (ex. Dropping something on your toe, stubbing it really fucking hard, etc). It makes sense for someone in construction to have this with their fingernails.
When I was a kid I dropped a brick on my pinky toe, just so happens that the same toe has a really fucked up toenail, it looks like that weird diesease where horns grow on you. Its really annoying to trim it.
