A portable fastener driving tool (10) has a raceway with a driver blade (21, 60) reciprocating therein from a retracted position to a fastener-driven position for driving fasteners (61) seriatim from a fastener-stick (19, 62) positioned on a rail (63) at an angle to the raceway. The first-to-be-driven fastener (61), while attached to the stick (19, 62), is positioned in raceway so that descending blade (21, 60) serves to orient the fastener (61) to a position substantially parallel to the raceway for driving it down and out of the raceway into the workpiece and also to deform the fastener for guided engagement with a front face (64) of the rail. The fastener-stick (19, 62) may be supported in raceway by detent stud means (29, 31) which retract from the raceway when staple (61) descends. The deformation of the fastener provides full contact with the front face (64) of the rail which maintains guided orientation throughout the driving stroke. |
