It depends on how a fan closes. The major idea is both of them compressing, which exxagerates the sharoness of the edge. And a fan represents the both as well. Furthermore, it could close into a bo-like staff with a sharp edge, which would be like an actual spear. Not to mention, fans have more potential for magical representation, which is really their style.
