Claim:
1. A deep rolling tool, comprising: a fork having a base section; a first fork arm extending outwardly from the base section; a second fork arm extending outwardly from the base section, the first fork arm and the second fork arm each having a distal end with respect to the base section; an opening extending from the distal end of the first fork arm and the distal end of the second fork arm to the base, the opening being located between the first fork arm and the second fork arm; and a first rolling element rotatably mounted to the distal end of the first fork arm via a first cantilever shaft that is angularly offset with respect to an axis of the distal end of the first fork arm, wherein the axis of the distal end of the first fork arm is parallel to the opening; a second rolling element rotatably mounted to the distal end of the second arm via a second cantilever shaft that is angularly offset with respect to an axis of the distal end of the second fork arm, wherein the axis of the distal end of the second fork arm is parallel to the opening; and wherein the first rolling element and the second rolling element apply a compressive stress to an article when it is located in the opening.
