New Piscator Sabiki Rigs.  The unique three-stage computer controlled tempering process transforms the hook into a fine grained, ultrastrong microstructure. This increases strength up to 30 per cent compared to conventional tempering methods. However, it's not only strength that is important in this process; Mustad has strict quality controls over the brittleness and flexibility of their hooks as well. Mustad's superior technology allows such control of the final outcome.
