"Bali-Song" has been trademarked by BM? Bizarre. How about "balisong," as used in Wikipedia
http://en.wikipedia.org/wiki/Balisong_(knife) ?

"While the meaning of the term "balisong" is not entirely clear, a popular belief is that it is derived from the Tagalog Language words baling sungay (literally, "broken horn") as the original balisongs were made from carved animal horns. These knives are also referred to as "fan knives" or "click clacks".
"Another suggested origin of the term "balisong" is its place of origin. There is a small town in Batangas called "Balisong" where the balisong is claimed to have been invented. Balisongs are handmade and forged there by makers using techniques passed down from generation to generation.
"The use of the balisong is so popular in the Philippines that an urban legend exists about every Batangueño carrying it everywhere he goes. They are a pocket utility knife used by people of Filipino society. They have also been used to fight duels over matters of honor, although such practices have been discontinued for decades."

I suppose, though, matters involving law and lawyers have little bearing on reality, or history, sometimes.
Interesting choice of words about the Bradley Kimura on that Knife Center web page: "
This is perfect for the butterfly enthusiasts who want a good product but dont want to spend the hundreds of dollars that quality American made ones will cost." Uh, what? Doesn't that imply that this Bradley is NOT made in the US? Or is he just implying that this one is simply not "quality made?"

Or maybe I'm just in a pedantic mood.
Meh.
