Silexus is inspired by the work of stonemasons. A block of stone becomes a useful everyday object under the hand of an expert sculptor: after finding the right point of impact to cause the shock wave, the splinter comes off and becomes a knife. But? What happens to the rest of the stone once all the blades have been obtained? Silexus is there any stone left after cutting. SILEXUS is not only a platform, it is a true eco-responsible innovation. It comes in two recycled materials: coffee grounds (black) and avocado kernels (brown).
