Modeled after the Albion Svante Nilsson Longsword: https://www.albion-swords.com/The%20Svante%20Nilsson.html
The page has very detailed description of this sword, which is based on an actual piece. The sword lies out of the Oakeshott Typology, and firstly it may seem like a fantasy sword from video games. The large ricasso near the guard is definitely something we don’t see very often on Medieval longswords.
