Given an arrow head symbol, formed by two lines, is there a name for each of these lines, individually? If not, perhaps a term that could be used to clearly convey that idea? For example: "arrowhead edge"?
If I had to choose among flavors, I would prefer a term that would be understood in American English.
Note: I'm getting answers and comments describing an arrow head. I don't want that. I want to know the name of a line that makes up half of an arrow head.
