Claim 12:
13. A fastener driver comprising:
a housing;
a cylinder supported by the housing;
a moveable piston positioned within the cylinder; and
a driver blade attached to the piston and movable therewith between a top-dead-center (TDC) position and a bottom-dead-center (BDC) position, the driver blade including
an elongated body having a first end connected to the piston, a second end opposite the first end, a first portion, and a second portion, the second portion extending along a longitudinal axis, the second portion having a top surface, a bottom surface opposite the top surface, a first side extending between the top and bottom surfaces and a second side extending between the top and bottom surfaces opposite the first side, the second portion having a first width defined between the first and second sides,
a plurality of teeth extending from the first portion of the elongated body between the first end and the second portion,
a common plane extending centrally through the elongated body between the first and second sides of the second portion, and
a tip portion defining a second end of the elongated body and configured to contact a fastener, the tip portion having a first tip side laterally offset the first side of the second portion and a second tip side laterally offset the second side of the second portion, the tip portion having a second width defined between the first and second tip sides, wherein the second width is less than the first width, wherein the tip portion is positioned closer to the first side than the second side of the second portion of the driver blade;

wherein the tip portion is bisected by a central axis that is parallel with the longitudinal axis such that the tip portion is laterally offset relative to the second portion in a direction along the common plane.
