Hornady, in this case.
Set of 8x57mm dies bought a good twenty years ago. The decapping rod was damaged a short time ago, entirely my fault(ran it into what turned out to be a Berdan-primed case). Searched around, couldn't find a replacement like it(smooth rod, newer are threaded). Contacted them, "Can I get a replacement for this rod, or need to buy a whole new assembly?"
Response: "You have an older die set, we no longer make that rod, I'll send you an assembly that'll fit your die."
I like companies like this.
