Report Review for product Nut File - Edge-Cut, for slotting guitar nuts

I bought two sizes of these small files, along with much larger Hosco file set that has 2 slot sizes on it (one on each side). My issue here is that they are very thin, small and harder to work with. They do work, and they cut well, but the are (relatively) paper thin. Not sure how long they will last, especially if I accidentally break one. They would get 4 stars if they were under $10, and 5 stars if they were closer to $5.
