CubeTraining is a Swiss-based self-defense training system that makes personal protection simple, easy, and rational. It enables instructors to teach effective “life-saving gestures” in just half a day using visual, scenario-based methods focused on awareness, escape, and powerful defense.
The core innovation is the patented Training Cube®—a modular pedagogical toolkit with panels simulating environments, didactic boards, dummy weapons, reference objects and striking surfaces. This is complemented by a detailed, illustrated instructor manual



A standout creative feature is clever negative space playfully evoking Jastrow’s duck-rabbit illusion to one of CubeTraining’s founders (an ambiguous figure seen as duck or rabbit). This optical play adds intellectual depth, aligning with the brand’s thoughtful, effective approach—simple at first glance, revealing strategic sophistication and deeper effectiveness on closer look.

Hey… this is Jastrow’s duck-rabbit!
