A few months ago, while reading about medieval weaponry, i manated to found something quite peculiar, which i never saw elsewhere apar from this document there (in french) : https://journals.openedition.org/crm/2511
It seems to be some kind strange, single-edged weapon, referred here as "épieux", that is said to have been very popular. Later, the author says it was also referred to as a "fauchard", which is quite strange since this one seems to have large knife-blade and a short handle, as seen above in the document, while it looks very similar to the "Maciejowski Glaive"
I would like to know if any of the users here knew something about this strange weapon, as i cannot find any informations about it other than the document above and that would really help me.
Thanks in advance to anyone who can help
