I would like to get a pair of the toughest knitting needles I can get, please.

Or afford.

They should be sharp, as in pointy ended, but still capable of being used as knitting needles. Also it would be awesome if they could be threaded into hair.

Either they have small caps on the end that can be removed or are enchanted to only properly stab when in contact with flesh. Else, they seem blunt.

Materials I'm interested in would be high quality wood and metal.

Basically as much as I can afford.
