Would formites please post the dimensions of any tri fullered export blades ... the type that tend to be fitted to Kaskara, Tabouka and Kattara. Length not so important as this dimension is likely altered to suit local tastes. The blade thickness and width would probably help to compare the blades ....as would the blade shape 'cross section' .
Charles has posted a Sumatran blade which looks very similar to the trade blades fitted to the above swords, it may be an anomaly but dimension comparison may prove/disprove the source of the blade

It may be interesting to see how far these trade blades travelled and to whom.
Thank you
Kind Regards David
