Mine didnt come std, but bought it as an extra for about 10 bucks Mystic Warrior 2. I have one on my other harness, so if i take either ou I am covered.
The only thing with carrying a knife, you have to remember where it is. The one on my dakine is on the back. The one on my Mystic is on the side towards the front.
Get to know the location just as well as your safety systems. Different kites have them slightly different configurations, so if you own different brand bars, you have a different safety, that may cause you to hesitate, when you really need It.
