Matt R-K has been studying historical martial arts since 2015. He teaches in the longsword tradition of Johannes Liechtenauer with a focus on earlier sources such as Ms. 3227a.

Paul began studying HEMA at Lonin in May of 2016. When the original KDF coach stepped away in 2019, as the most senior student, Paul stepped up as one of two co-coaches to keep Lonin’s KDF practice going.
