More, just for grins and giggles (by the way, did you look up the Cawood sword?) hre are three modern threaded tangs. Ironically, or not, the widest blade has the narrowest tang and the narrowest blade the widest tang. All three swords have been through the mill of some pretty serious abuse. The Oscar actually used to pound on armor strapped to a side of beef (honest injun). The Del Tin I use around the yard and was actually limbing small branches from a fallen tree last year. The Windlass has had an enormous amount of use and granted a thicker thread but the construction is the least of its issues.
If that's not enough ear tweaking, consider the big falchion next to them on the left is threaded as well. Also the two Angus Trim and two Arms&Armor swords further back on that table. The Patton 1913 sword on the other side is Windlass and as full a tang as you can find. I think they retail for about $169 these days.
Happy hunting
