The quintessential weapon of KdF is the longsword, a roughly 48 inch, double-edged, well-balance sword. Despite myths of being a clumsy weapon useful only for bashing, a longsword averaged about three pounds, and was capable of lightning-quick cuts, thrusts, and slices. But the techniques learned with the longsword are not useless elsewhere. The principles of KdF apply equally well with the longsword, unarmed grappling, or any of a variety of weapons used at the time. These include dagger, messer (falchion), spear, poleaxe, buckler, dueling shield, mace, flail, and the list goes on.
Although Historical European Martial Arts died out or evolved into gentlemanly sports with the advent of effective firearms, modern historians and practitioners are reviving these traditions. Thankfully many masters left written records of their teachings in text, pictures, or both. Dozens of these works survive, allowing modern students to resurrect these dead arts.
