Quartermaster QBS-2P Marty McFly Butterfly Knife (4" Satin) QTRMSTR B2TF2

What will it be, a butterfly knife with a razor sharp edge or a trainer blade? The Marty McFly QBS-2 from Quartermaster makes it possible to have both while offering great flipping action. Their patented BladEXChange feature allows the user to remove the handles from one blade with a push button release, and quickly attach to another blade. The QBS-2P includes both a satin finished "live" recurved blade and a dull trainer blade. Handles are satin finished titanium and include a pocket clip and titanium latch.
