The Brous Blades Sinner is a limited collaboration with Sal Manaro, based on his custom folder. It has a satin finished D2 steel blade with a swedged drop point and flipper. Brous Blades' proprietary ball-bearing system is employed to give it sharp action to match its looks. Twill-weave carbon fiber scales adorn the titanium liner lock frame with a bead blasted, checkered titanium back spacer to bring it all together.
