A rather simple system this time : slip joint. We don’t really need a lock if we mostly use a knife for food.
Carbon fiber liners, much lighter than steel. Armed and twice stabilized concrete scales. I wanted to play with this material so I broke the concrete in various places and let appear the metallic net underneath. The acrylic resin then flattened the surface, giving a smooth touch but still allows a perfect reading of the material. It all brings a strange contrast, between sophistication and decadence.
Another original feature, we designed a new composite type of spring, assembled like a sandwich around a thin layer of G10 (glass fiber).
Without harming the functionality, we achieved to save about a third of the metal weight. Even more, we chose titanium screws on the pivot, lighter than steel.
