Repros were made. The same fellow who commissioned the reproduction fuses and Bormann wrenches from a fellow in Utah, commissioned some of these. A distinguishing characteristic is that on the repros the iron blade doesn't protrude through the brass handle and show as a small rectangle. The one on eBay has this mark and so presumably it is not a reproduction, but I cannot be absolutely certain.
As a result of these repros showing up and confusing the market, the price for legitimate ones has fallen to more like $150, and they are tough to sell at that.
