Peter Johnsson's expertise goes well beyond viking blades. He has measured and weighed swords of many types, in many of Europe's finest museums. His first sword was a replica of the Svante Nilsson Sture sword which was exactingly accurate in every detail. I am glad to count him a friend, and his work is outstanding, no matter what it is that he makes. Seax are very interesting blades to make and to play with.
