All you have to do is throw the Real Knife into a dumpster like the useless piece of trash it is and get the Burnt Pan instead, then have your inventory contain Butterscotch Pie, Instant Noodles, Steak in the Shape of Mettaton's Face, three Snowman Pieces or Legendary Heroes, and Sea Tea. Then practice, practice, practice. Unlike Undying, Sans' attacks are not randomized, after enough trying you'll learn his patterns. You have the edge on his boss fight. That's basically what has been written in the original post =))
