Fuller’s soon-to-be-released “bullet blade” takes its name from it’s double curved head.  It looks more like a Volkswagen Beetle to me, but its most important feature is that fact that it accepts special double-headed blades which you can deploy from either end.  It also has on-board storage for six additional blades. 

It’s always fun to see tool designers incorporate design elements from other objects. You just know that someone at Fuller looked at a screwdriver, and thought, “this needs to be more like a revolver.”  The result: the Switch-A-Bit 10-in-1 multi-driver.
