A Strange Moro Twistcore Blade

[CharlesS]

This well worn Moro blade is naturally fascinating because of it nicely defined twist core, but it has some interesting odd characteristics as well. For instance, I cannot figure out the need for the clamp and pin between the blade and ganja. I would think it would be associated with the tang, but for what?

Also, why add a fuller to the bottom half of the blade??? To me it is just a distraction from the lovely twist core. Would a fuller really lighten the blade that much. It's hard to believe that removing just that much metal could have played a major factor in the kriss's balance, but I suppose not impossible.

Ideas and comments are welcomed.

Dimensions:
Overall length(no scabbard) 29.5in.
