The tail point is sharp enough that my part lines come out clean every time, no snagging. I've used it through several color touch-ups now and it hasn't warped or gotten brittle from the chemicals.

Used this to section my hair for a bleach and tone last weekend, and the tail end slid through wet hair without snagging once. It didn't warp or soften even with the developer sitting close by.

The fine teeth are perfect for clean sectioning, and it hasn't warped once despite the flat iron heat nearby. I've used it through several dye jobs too and it shrugs off the chemicals fine.
