The Path Maker is used to provide a smooth raceway for the thrust bearing balls to slide along. The Path Maker is used in a drill press to mark the raceway into the blade and liners. This task is performed by setting your drill press at 500 RPM and applying a light down pressure for a few seconds. Check the surface for marking until a circular raceway is visible, then this task is complete. We recommend that you complete this task to the blade before and after heat treat to guarantee the elimination of all tooling marks. You will need a different Path Maker for each bearing size and each pivot size that you use. The final assembly should use new bearings only.

GTC 440C stainless steel thrust ball bearings caged in stainless steel retainers developed and patented by Gustavo T. Cecchini's GTC Knives to reduce friction and failures, increase opening time, and easier cleaning. The 100% stainless steel construction eliminates the problems of other thrust bearings that are not 100% stainless. Install by cutting a pocket, with a counterbore, in both the blade and frame. Use one bearing in blade and one in the frame. Some prefer to cut the pocket in both frames, and not in the blade. This is a good solution when the blade is already hardened. Sold Each.

The illustration (above left) shows the pocket in the left liner once the procedure has been completed. The first bearing will fit in this pocket. The second pocket should be cut in the blade. In final assembly (see above right), the liner pocket and blade pocket should be facing up when the knife is in the proper position for assembly.

There should be a raceway path on each side of a thrust bearing. The illustration above shows the right liner with the raceway path completed. This raceway matches up to the blade pocket
