Buy a new nut at your local guitar shop. Tip: Make sure it's big nough for watever guage you wanna put on. Ask the salesman bout it. It is his/her job to know guitars.
a pocket knife? you didnt have a small wood file or nail file on hand?

I wish you would have just left it at "My Nut Broke".... Sorry. That was inappropriate.
