The Cypres has a unique method of opening the reserve container, using a device that cuts the reserve container closing loop. It is completely independent from the normal reserve container opening system.
While a jumper uses the reserve ripcord handle to pull the reserve pin out of the eye of the closing loop, the Cypres uses a cutter which cuts the closing loop itself.
This autonomous design has saved the lives of skydivers with damaged reserve pins. After an activation, a replacement cutter can easily be plugged in.
