I've seen several people comment that Tobin was the only one that seemed to be having fun on the show.
I'm just impressed they left in Tobin's explanation of his idea for the cutlass being an espada ancha that had been re-handled by a local smith in the New World (which happened a lot, some of which used a rolled iron tube similar to Tobin's pipe handle) and wrapped with some hemp cord by the pirate owner.
J. Rosa - I hadn't heard of the espada ancha prior to Tobin going on the show. Once he told me the name, I did some Googling and came across a number of examples in collections or up for auction, and a decent percentage of them had the rolled iron tube handles. They were in use for decades or even centuries after leaving the Old World for the New and would get cut down shorter and re-hafted sometimes several times. The older ones tend to have straight blades, while the newer ones are often curved.
