Derivation of the Balisong knife is from the Philippines Islands. As shown the knife is interior to the handles but a skilled user can 'flip' it open very, very fast!
Correct.
However, in the Court decision, it is noted that in expert hands, the Balisong is a little bit slower to open than other style lockblade knives in expert hands.
I had a friend in high school who had one. He kept it in his boot. He could pull it and have it opened in a blur.
Which does what though? I can carry a thumb assist or a fixed blade and deploy it even faster. Balisongs are only scary to boomers that watched to much TV. Its no more real that a single bullet causing sudden aircraft decompression or a bullet tossing a human target 6 feet. Its nonsense, junk, things immature minds believe like a monster under the bed.
