Riddle: With pointed fangs it sits in wait, With piercing..

With pointed fangs it sits in wait, With piercing force it doles out fate,
Over bloodless victims proclaiming its might,
Eternally joining in a single bite
What is it?

Answer: Stapler

A stapler has pointed fangs (the metal prongs) that it uses to pierce through paper and bind it together with a staple, and it can be seen as delivering a “bite” to the paper.
