re: "Called the heel here"
Also "heel" in the part of the Midwest I was born into, and carried with me since: a loaf of bread has two heels, and no toes.
Codo (elbow) makes just as much sense -- perhaps a little more, depending on the shape of the original loaf. Baguettes, being long and skinny, have pointy ends like an elbow.
By any name, coveted by connosieurs who like extra crust.
