Knight and Pawn Ending

My nephew and I were looking over this position and wondering if it was a draw.  It seems like it to me.  If it is, I wonder if with a little variation it would be winable by white?

I just came across a post by likeforests, The Endgame Tactician: Knight vs Pawn and I'm wondering if he would have some insight so I'll post a link in his comments (for some reason I can't add a chess position to a comment).
