As weapons, they are also easier to enchant as a Golem's Immune-to-Magic slam would be, which is also a plus. So… Given the lack of iteratives, it doesn't scale very well, but I'd call it strictly superior to either normal slams or normal weapons used with its one iterative. Also, I believe they are not part of the creature. The description says scimitar-wielding, not scimitar-welded.
That doesn't make it +0 material, though, at this number of HD. I'll give you that.
