Is there a collaboration between Gatco and Spyderco for the Tri-seps pocket sharpener? It looks exactly like the material of the Spyderco medium stones.
By the way, the great thing about this sharpener is the larger radius that it has on one of its three edges. That makes it great to sharpen the larger grooves of most serration patterns, or repair chipped serrated blades that have been abused (or made from very brittle material - Spydercos do not have this problem but "others" do)
