A hair splitter is a person who is overly concerned with trivial or unimportant details. In the context of crossword puzzles, a hair splitter is someone who insists on using obscure or difficult words or phrases, even when simpler alternatives would suffice.
Hair splitters can be frustrating for other crossword solvers, but they can also be a source of amusement. After all, it's hard to resist a good groan-inducing pun or a clever play on words. And sometimes, a hair splitter's insistence on precision can lead to a more challenging and rewarding puzzle.
