I recently got some hairsticks from Clairs at our mall, and I rather like them. They're metal(I suppose) and they stay well in my hair, but the ends(the buissiness end, not the decorative ends) are too blunt and flat, they catch hairs as I try to weave them in. I'm afraid they'll snag and break some hairs so I try to be very careful when I do wear them. Would there be a way to fix up the ends so they might not be as bad to wear?
