I'd take espada y daga as a pretty clear influence of the Spanish fencing methods. Not just the term itself. We all know that applying a foreign term to an indigenous art doesn't imply relationship. The British calling gung fu "Chinese boxing" doesn't suddenly mean that there's an ancestry from Western boxing to gung fu. But the idea of fighting with one longer weapon and one shorter one isn't a common idea in Asian methodologies. At least I can't think of too many examples. There's ni ten ichi of course. But the way espada y daga generally works is very different from the way someone would fight with a katana and wakazashi.
