Hi. I'm Mike Patrick, and I'm going to teach you how to do a charlier cut. First you go into straddle grip. That means that you have your index finger on one end, your little finger on the opposite end. Your two fingers should be over here, and your thumb is there. The grip looks like this. It's very secure.
And what you're going to do for the charlier cut, you have two ways of going into it. You can release pressure with your thumb, and then you bring your index finger in the front, and you're going to kick it up. So at speed it looks like this. It's important to keep your pinky at the back. The reason why it's so important is that it will hold the packet stable. If I don't have my pinky there, it's more liable to fall like this or maybe like that, and if you did a few of them in a row, you'd start having this mess. Whereas if you keep your pinky in position, you can use gravity to help you maintain a square deck. It looks much better this way.
So every time you come down, you're going to release the cards from your thumb, and then you're index finger is going to simply kick this packet up until your thumb can get out of the way. It clears, and then you let go, and it falls down and collapses with itself. The alternative, which gives you a little bit more control over how many cards you take off of the packet, is to take that index finger and use it to literally pull a packet down and then kick it up. This allows you to take a small packet, if you're doing a triple cut variation, or you can take a larger packet, or you can just control it so that it's a perfect even packet. A lot of the time, I just usually use the falling method, using pressure.
It's entirely up to you, and it really is on the context of what you're using it for. But that is how you do a charlier cut.
