1. A table saw comprising:

  • a table defining a work surface;

    a substantially planar, circular blade configured to extend at least partially above the work surface;

    an elevation carriage;

    a riving knife or spreader, where the riving knife or spreader defines a plane; and

    a clamp system supported by the elevation carriage, where the clamp system is configured to hold the riving knife or spreader adjacent the blade, where the clamp system includes a plurality of mounts, each mount having a head portion, a flange against which the riving knife or spreader is clamped by the clamp system, and a threaded portion adapted to screw into a socket associated with the elevation carriage, where the flange is between the head portion and the threaded portion, where the head portion is accessible by a user, where the clamp system also includes a clamping surface where the riving knife or spreader is clamped between the flanges and the clamping surface, and where the position of the plane of the riving knife or spreader relative to the blade when clamped in the clamp system can be adjusted by the user accessing the head portion to turn one or more of the mounts to reposition one or more flanges.
