The PowerDuo is a hybrid between SOG's knife mentality and tool sensibility. It has a split personality. It is neither knife nor tool, but an equal combination of both nested in a compact form. Take away the pliers and you have a multi-blade pocketknife with a full size locking blade, screwdrivers, can/bottle openers, tweezers, etc. Take the knife side away and you have SOG's renowned Compound Leverage pliers with one-handed flip opening capability. Put the two together and the PowerDuo gives you options in an ever-changing volatile world.
