The Grand Master Extreme employs a 0.22mm square one-piece diamond cantilever, where the diamond cantilever and the needle tip are crafted from a single diamond. Typically, the diamond tip of the cantilever and the needle tip are bonded together using adhesive. However, with the one-piece diamond cantilever, the cantilever and the needle tip are integrated into a single unit, enabling a more direct transmission of information from the needle tip.
