A cork (also known as a corkscrew) is a slant gainer with full twist. It is seen in tricking as well as in free running. It is most commonly done from a j-step setup, however it is possible to perform one from a scoot, pivot or swingthrough setup.
 Common Variations
 Oldschool Cork
An oldschool cork is a cork without the flip, a btwist from a gainer set-up. Instead of kicking towards the opposite sholder, the swinging leg is kicked towards the opposite hip or bellow. It is very hard to swingthrough out of it.
 Hyper Cork
A hyper cork is an over-rotated corkscrew which is landed on the swinging leg.
A boxcutter is an hyper cork followed with a hook kick done before the take off leg meets the floor.
 Double Cork
A double cork is a cork with an extra spin, a slant gainer double full.
Most cork variations can be done with a double cork (hyper, double leg, boxcutter, etc.) although not all of them have been landed yet.
