The blade doesn't have to be straight, as some have a curved blade, rather like a scythe. The blade is also usually shorter than the athame. I have seen bolines made from a variety of different materials, my own has a handle made from the tine of a white-tailed deer and the blade is short, curved and kept very sharp.
Element: I am not aware of an elemental association attributed to this tool, but I assign it to Earth because of it's uses.
Uses: The cutting blade for ritual use, this knife is for inscribing on candles, cutting or harvesting herbs, cutting cords, cutting wax, etc. Some traditions specify that this can only be used in circle, ours only specifies that it be used for a ritual purpose, such as cutting flowers from my garden for use on the Altar. They are a very handy tool to have.
