Despite the idiotic name and packaging, those are actually decent balisongs (the proper name for "butterfly" knives) made by Taylor-Seto in the 80's. They're called "Manila" folders because the latch is on the "safe" handle (the style common to Manila, Philippines), as opposed to the Batangas style, where the latch is on the "bite" handle (this style is far more common with modern balisongs). It's hard to see from the photos, but it looks like one knife has brass handles, the other has steel.
I'm no expert appraiser, but my guess that this set might be worth around $100-120. If they were mint and didn't need cleaning up, maybe $150. Pretty rare set.
