A three-way spring clamp is provided that is useable as an edge clamp for applying clamping forces to workpieces in three directions. The clamp includes two lever arms, each having a jaw end and a handle end. The lever arms are pivotally connected to each other at a pivot point located between the jaw ends and the handle ends such that the lever arms can be moved between a closed gripping position in which the jaw ends are proximate to each other, and an opened position in which the jaw ends are spaced apart. A coil spring is provided for biasing the lever arms toward the closed gripping position. A spring engagement member is mounted between the lever arms. The engagement member includes a central body portion engageable with a surface of an article to be clamped. The body portion is positioned between the pivot point and the jaw ends and may have a generally concave configuration from the perspective of the pivot point when the lever arms are in the closed gripping position. The engagement member may be configured to snap into place between the lever arms. The engagement member provides spring pressure in a direction generally perpendicular to the direction of clamping forces applied by the jaws of the clamp, making the clamp suitable for use as a three-way edge clamp.
