The St. Mark Koning Glove is one of the new hot five fingered gloves on the HEMA market. Axel Petterson and Anders Linnard two really high profile fencer in the HEMA community developed them to be used for longsword and other weapons. I think they debuted at Swordfish 2015, and started to ship them by the end of March, 2016.
I haven’t had the pleasure/opportunity of trying them out, but I collected some reviews, videos and text about it for you.
