aint it a hand and a half as Ginger says? or a one handed handle but with a big pommel to get your other hand around? that longsword looks too unwieldy to use one handed which is what characterises a bastard sword. Versatility.

a bastard sword is often a hand and a half handle

You may be very well correct, but I have found several sources online that characterize a bastard sword as...:

"The Medieval Bastard Sword generally had a long handle which allowed for two-handed use and a longer blade."

Don't want to step on anyone's toes, but as a HEMA practitioner and historian, this is a longsword.

Still, very beautiful.
