Diva Precision Shears employ a unique process that Japanese craftsmen have been developing for centuries in the art of creating the samurai sword. Using the ancient lost wax process, premium cobalt alloy stainless steel is put through a triple tempered process that allows the Diva Shear to hold it's superior edge. Japanese craftsmen hand finish and then align each shear for uniform pressure when blades are opened and closed. Diva's unique Clicker Adjuster system uses a tension leaf spring design to adjust tension of blades in precise levels of variation.
