Ah, the tride and true metal nail file. I’d say most people who have some sort of nail kit has probably recieved this one as part of it. It’s reliable, it’s reasonably priced and it’s always convenient to have.
However, the metal nail file is sort of like a double edged sword.
On one hand, it is a great precision based file for your nail. It doesn’t take a long time to get your nail to the desired shape you want with this file. With a bit of pressure in the right direction, the nail smoothes down faster and more accurately than the glass nail file. Also, unlike emery boards and glass files, it doesn’t leave that many scratch marks on the steel. (At least the kind I purchased did not. I’ll link it below.)
On the other hand, the metal nail file isn’t very good for your nails. The metal may not handle your nails the way you’d want it to and they seem to chip and crack your nails easily. It all depends on the technique of course, but if you’re not used to filing your own nails- I’d say start with emery boards before you upgrade to heavy metal. I will say, whenever my nails do chip or crack on their own, I rather the metal nail file over a glass file just because the metal is able to maneuver better.
All in all, a metal nail file is good to have as a backup tool for any Varnishta- but don’t go overboard!
