How should I handle a supervisor’s favorite coworker who keeps talking down to me?

This coworker is much older than me and I’ve been there longer than him. Yesterday we were fixing a fence. He asked me to cut pieces of this metal fence ties. I guess I wasn’t going quick enough because he said if I can’t do it he’ll get someone else to do it. And he always complains how I do my job. How I don’t do it the right way.
