A gas spring-powered fastener driver includes a cylinder, 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 driven or bottom-dead-center (BDC) position. The driver blade defines a driving axis. The driver blade includes a body having a first side and an opposite, second side with the driving axis passing therebetween. A plurality of teeth extends from the first side of the body. A plurality of projections extends from the second side of the body. The body, the teeth, and the projections are bisected by a common plane. A lifter is operable to move the driver blade from the BDC position toward the TDC position, and is engageable with the teeth. A latch assembly is movable between a latched state, and a released state. The latch assembly is configured to engage with the projections.

A fastener driver includes a housing having a handle portion. A motor is positioned within the housing. The fastener driver further includes an air compressor including a compressor cylinder and a compressor piston movable within the compressor cylinder in a reciprocating manner to compress air within the compressor cylinder. The fastener driver further includes a drive train converting torque from the motor to a linear force applied to the compressor piston, causing the compressor piston to move in the reciprocating manner. At least a portion of the drive train extends through the handle portion of the housing.

A wear member for earth working equipment and a wear assembly including a plurality of such wear members. The wear member defines a longitudinal axis and comprises: a body defining a rearward opening cavity dimensioned to receive a base; first and second lateral portions extending from opposing sides of the body and defining a front edge for engaging earth. The first lateral portion defines a complementary formation to the second lateral formation to enable axial insertion and removal of a wear member mounted between adjacent wear members due to the open removal path defined by the complementary formations. The complementary formations also resist rotational movement of the wear member about the longitudinal axis.
