Which one of these is not a typical European sword design?

The story behind the answer

Scimitar is correct because it refers to a family of curved, single-edged swords from the Middle East and Central/South Asia—think Persian shamshir or Ottoman kilij—rather than a European design. European swords were typically straight: the falchion was a medieval, single-edged European blade; the flamberge had a distinctive wavy “flame” edge used on some rapiers and two-handers; and Ulfberht isn’t a type but a famed inscription on high-quality Viking/Frankish swords.

A handy memory hook: curved blades = Eastern cavalry slashing; straight blades = European thrusting and cutting in armor-centric combat. So when you see “scimitar,” picture mounted warriors from the Islamic Golden Age and Ottoman Empire, not medieval knights.
