Having bought multiple cooking utensils in the past few years, I don't recall seeing one in a box that said "kettle". From what I can gather, that is pretty much an archaic term, and only used in a context such as tea kettle; however, the latter is just as often called a tea pot. If I look around in a store, they will have things called sauce pans (nothing to do with a pan), stock pots, and Dutch ovens (nothing to do with an oven). I may be wrong, but to me a kettle is a pot with a wire handle like a bucket. No reason you could not cook spaghetti in it, if you found one.
I am still trying to figure out what the previous poster meant by aligning the pasta.
