Arcane Needle

A needle that never bends, even when pushed through solid objects.

This needle is imbued with the Mending spell and can pass through stone and metal as if it were cloth. Does 1d4 improvised piercing damage if used as a weapon.

Additionally, when held up to a lock the needle can be used to "pick" the lock via the Knock spell. This action can be used once per day.
