Sorry I can't offer a good alternative to the factory clip, but how about taking a dremel to the clip to remove all or one or two of the letters? Given the lightweight use of the clip I wouldn't expect it would be weakened enough that it would render it too bendy or useless.
You could leave it saying "SO" or "S G" and if anyone asks you could tell them it's an abbreviation of your forum name, "Strobengh". Of course that would lead to "what forum?" and you'd then say "BladeForums.com" and then the jig would be up, but still...
My two cents, possibly worth much less.
