MYSTIC SAFETY KNIFE
The Mystic Kite Safety Knife is compatible with all Mystic harnesses and many other brands too. The guarded blade ensures you cannot damage yourself or equipment accidentally but is still incredibly sharp to allow for cutting of lines in an emergency.
The knife blade is stainless steel to prevent rust in the water, small webbing handle for easy grip and comes with a pouch with belt loop. Alternatively it is compatible with most harnesses that have a knife pocket.
The knife should be mounted on the front of your harness somewhere that you can always reach it.
