Okay, again a tutorial. This is for "The Killermove". Funny name, not an easy move, but looks nice I think.
This is the Link:

Explanation:
You start at the normal open forward grip position, bite handle out. Then you flip it like you want to do the basic clothing but instead of clothing it you grap the save handle with the thumb and indexfinger and put your middlefinger next to the thumb (inside). Then you twirl it one rotation with the indexfinger and middlefinger, roll it one rotation around the middlefinger and insert the thumb, rotate on one rotation with it, grap the bite handle with the blade and throw it a half rotation, you grap it in the normal open forward grip and can do the trick again for example.
Success while learning! As I said, it`s not easy but looks cool when you have it!
