Hello Jens and Fernando,
My issue is not so much related to the quality of the blades as high quality blades were manufactured both in Europe and in India, but more with the TYPE of blades manufactured.
My point is that the Pata requires a very specific type of blade, long, wide and very, very elastic that is incompatible with any type of European or otherwise sword I know.
Now Jim has mentioned the Kattara (sounds like a type of Katar
), but I am not familiar with this type of sword and I am planning to research more about it. However, there might be the possibility those swords use imported Indian blades, rather than the other way around.
In my line of logic, I believe that since the Pata blades were that peculiar and specific, it would be most logical they were manufactured locally, even if some of them were adorned with European-like decorations and markings. In other words, I find hard to concieve that European swordsmiths were producing this type of very special blades specifically for export to India.
Yes, there are some, maybe many, examples with Patas fitted with European rigid blades, but those Patas would have been extremely difficult, impractical and ineffective as weapons.
