Well made point Mercenary, and very good analogy.

As you say, the Indians certainly used European blades significantly, but probably did so out of convenience in most cases. I most cases trade blades were conveniently available but probably they preferred their own blades as a rule as they knew well what quality they put into them. It still does seem interesting that they used European markings to their own blades though.
Why, if they had such high regard for their own blades, would they add spurious European marks and inscriptions to imply 'quality' ?
