That fictitious fellow wielded a two-handed broadsword, IIRC.
This looks like a one-handed sword.
Not much less lethal, though, probably.
Most of the bronze age swords were short swords. Bronze was not strong enough to make blades as long as later iron swords. I have three bronze age short swords, two metal handles and one tang mount that probably had a wooden handle. The two metal handles are about 16 inches overall and the tang mount is 17 inches from tang to tip so I estimate it would have been just over 20 inches overall with a wood handle.
