Minor strokes in the shape of 八 or 丷, as in the top of 𠔉 and 龹, can be referred by this radical (but in many cases, it is a false friend). These are often written as 丷 in modern texts. Compare 卷/卷, and different forms of 鬲/鬲.

Ideogrammic compound (會意 / 会意) : 八 is two bent lines indicating the original meaning of "to divide". This character is later borrowed to mean "eight" because of homonymy, making the original meaning obsolete (now represented by 分 and 別).

Unrelated to the bottom part of 兵, 共, 具, and 兴, in which it represents two hands holding an object. Also unrelated to 只 and 兑 in which it represents air coming out of a mouth. Unrelated to 貝. Eventually, unrelated to the bottom part of 其, 真, and 典, in which it represents the legs of a table.
