It looks like most falchion handles are too short for 2handed grips, but I seem to recall a video of John Clements using a curved weapon (falchion? longmesser?) with 2 hands cutting a flying tatami mat.
Are there any Western treatises specifically about using a single-edged weapon with 2hands as opposed to just applying longsword techniques to a 2handed messer?
EDIT: Renamed title for accuracy.
