Difficulty: Moderately Easy
Step1
Extend your right hand as if you are preparing to shake hands. If you are left-handed, this will be reversed.
Step2
Lay the knife lengthwise along your second finger joints and curl your hand in, with the thumb just under the catch of the knife.
Step3
Flick the knife upward as you open the blade with your thumb. Be sure you flip the butterfly knife to your right if you're right-handed and to your left if you're left-handed.
Step4
Squeeze the back end of the butterfly knife against your fingers and thumb, as you allow the front half and the blade to drop. Flip your wrist quickly so that the front half of the butterfly knife flies up and strikes the back part of your fingers.
Step5
Hold your forefinger against the knife as you remove your other fingers, and allow the front piece to strike the back part of your index finger. The front piece has now taken the back position.
Step6
Put your fingers in a curled position again, to hold the back piece of the butterfly knife in place as you slip your index finger off the top. Use your thumb to latch the knife.
