I have a 940 that I have been carrying for 4-5 years. It is very pocket worn, the handle has a deep groove worn there by my pocket seem under the clip. The blade has been sharpened so much that the blade profile is signifigantly different than my other. The green finish is dead smooth, no hint of texture left. Even the purple anodize on the back strap is nearly non existant. I was considering sending it in for the factory sharpening. Just wondering if anyone else has done it, and the results. My boy lusts after one of his own, so if I don't send it in, I may pass it along to him and carry my new one.
