This research presented by J Cagnot (PhD in medieval archaeology) in 2013 at the Sorbonne University. It is the most recent work I know in the field of medieval weapons in French Language.
This work about more than 700 pages is well documented with a lot of detailed pictures.
Also an unusual late medieval sword type: Swords with an overly long ricasso and a huge, solid disc-*‐shaped pommel presented during the conference” the sword form and thought” at Deutsches Klingenmuseum Solingen.
