I've always hated that half moon also, I never removed it cause they said awhile back that it was there for a reason, but that reason never surfaced
I remember that thread over on BladeForums; that's one of those secrets I'll never understand. If it's something really cool, then announcing what it is would increase Waki demand (while you're selling them), or why mention it at all if it's lame? Months after the fact, it just makes you wonder if the product in question will turn out to be vaporware.
