In the event you use them....
Centaur Forge (www.centaurforge.com/) appears to be dead, in terms of actual business transactions.

Centaur Forge LLC

Burlington, WI 53105

No longer answering inquiries, no longer honoring prepaid shipments. WEBSITE is alive.... I believe it is a zombie.

Centaur Forge's website is still alive. I thought the company makes and sells swords before realizing that it only supplies blacksmithing products.
