Don't fret, I did that myself once (about two days ago, right here in fact).
What it tells me is that 'negotiations' for a sword should properly begin with "excuse me while I hammer this thing against whatever affords itself in the next ten or fifteen minutes"
I'd be just tickled to have one of those "cheap German knock-offs" just the same.
PPS: Ulfbehrt is a silly name, but I doubt very many people told him that.
