Balisong/Butterfly: A knife design believed to have originated in the UK, brought to the Philippines by English sailors, and was adopted and popularized in the Philippines. Often used in Filipino martial arts. The knife has two separate handle sections that rotate round the blade's pivots to create a handle and then rotate back covering and protecting the blade when closed.

Flat-Saber Grind: A knife's edge, ground completely flat without a radius that tapers from the cutting edge to a grind line down the center of the blade. Unlike a Full Flat Grind, which tapers from the cutting edge all the way to the blade's spine the Flat Saber only is flat ground just to the grind line.
