What is the difference between a bastard sword and a longsword?

 Updated Mar 2026

The bastard sword, historically known as a hand-and-a-half sword, was engineered to serve dual grip configurations. The hilt is long enough to accommodate both hands but short enough that a single-hand grip remains practical, giving the user flexibility depending on context. Blade length typically falls between 33 and 40 inches. The longsword, by contrast, was designed from the outset as a dedicated two-handed instrument, with blade lengths commonly ranging from 35 to 47 inches and a hilt sized specifically for a full two-hand grip with no ambiguity. From a collector’s perspective, the bastard sword presents a more compact and versatile display profile, fitting naturally on a mantelpiece or shorter wall bracket, while the longsword demands a larger dedicated display space and reads as a more imposing centerpiece. Both forms are well-represented in 14th- and 15th-century manuscript illustrations and surviving museum examples.
