““A good cook changes his knife once a year because he cuts, while a mediocre cook has to change his every month because he hacks. I've had this knife of mine for nineteen years and have cut up thousands of oxen with it, and yet the edge is as if it were fresh from the grindstone. There are spaces between the joints. The blade of the knife has no thickness. That which has no thickness has plenty of room to pass through these spaces. Therefore, after nineteen years, my blade is as sharp as ever.””
