One-Handed Spring is a niche variation of the Spring. Its mechanics are similar to those of the traditional Spring, but the challenge lies in thumb placement. The thumb must be positioned precisely to allow the remaining cards to release smoothly, as they tend to catch against the fleshy pad of the thumb.

One Handed Triforce is widely regarded as one of the most difficult moves in cardistry. It is a highly complex structure built from three interconnected triangles forming a stable formation. The construction process involves carefully separating additional packets and gradually sliding them into place under controlled tension. Origin Antoine Thomas tells the story of the trick: I did play legend of zelda myself and forming a one-handed triforce is an idea that has been tickling that fractal-friendly mind of mine ever since I did my first square struct. The complex nature of that particular structure obviously wouldn't allow me to do a quick and flashy formation, yet I wanted something pleasing to watch... The solution was to make the formation itself a crazy recasting sequence, made of structures like the pentagon, the square in pentagon, the house, and the triple triad, leading to that dream-come-true climax.
