The Chevalier is named after the French term for "knight" (from the French cheval = horse; Old French chevalier; from Late Latin caballrius, horseman; Middle English chevaler; Modern English, cavalier.)
A classic Medieval cruciform sword in design, with its long blade this would have excelled as a horseman's sword.
The Chevalier is classified as an Oakeshott Type Xa. Oakeshott describes the typical Type Xa as a broad flat blade of medium length with a narrow fuller (narrower than a typical Type X, but not as narrow as a Type XI), running the entire length of the blade.
The Chevalier's blade is inspired by a beautiful sword in the Wallace Collection (London) with a hollow-ground cross-section. Scholars generally have dated this sword to the 14th century, but Oakeshott in Records of the Medieval Sword argues that it is probably much earlier -- between 1050 and 1150 AD.
The hilt design is inspired by the famous miniature by Matthew Paris (a Benedictine monk and chronicler), c 1250. The pommel is a scalloped wheel resembling a flower, the guard is a flattened diamond in cross-section. The grip is standard with a diamond-pattern strap overwrap secured with pins.
Though the point is narrow enough for thrusting, this is principally a cutting sword, designed for use against opponents in mail armour. This is a unique design for a Crusader era sword, elegant and yet still brutally functional.
