Hi. My name's Dan Delavan. I'm the owner/operator of Plaza Cutlery in Costa Mesa, California. We have a great selection. We also have a website, plazacutlery.com. And today, we're gonna be talking about knives.

Butterfly knives are originally from the Philippines, made famous in a lot of martial arts movies, and used in martial arts. Unfortunately, in the state that we're in, California, they're illegal and they're considered a gravity knife. But, this is a trainer and basically, the handle is two pieces, with the pins in it where it pivots up and over the blade. Some knives will have a latch, some will not.

There's different qualities from low-quality $10 ones, on up to a couple thousand, you know, for a custom made. There's a number of custom knife makers that make some really high end ones. When you get into some of the Damascus, you can get up to a couple thousand. So, there's all different ranges of butterflies but again, check your state and see what's legal.
