Life version of Sunqua Blade?

Ok so for some of my art and stuff I've needed various short styled swords that look workable for dual wielding. Just wondered what the most life-like version of the Sunqua blade is, the Spartan swords seem to be too big and jagged.

Real life blade? As in, real, actual fighting knife? I'd look at khukuri/khukri knives. Google has a ton of images.

There are a million similar knives, but they're morefantasy knives and daggers, not made for practical use.
