I met Roland Warzecha (also known as Dimicator) at the first Swordfish event, in Malmö in 2006, and we have been friends and colleagues ever since. He has built a first-class reputation in the fields of I.33 sword and buckler research and Viking sword and shield combat. He is a graphic designer by profession (he consulted on the card design for Audatia), and produces extraordinarily well presented research on sword design and related topics in his 800+ patreon posts.
In our wide-ranging conversation we discuss how he got started in the sword world, his early training influences, Viking sword design, and many other things. Specific links: we mention the Berlin Buckler Bouts, and historical sword hilt manipulations.
