I have used the shit outta my necker. its in the rotating EDC collection. its double chiz and I think D2. it was forever before I needed to sharpen it, and I had beat it like a redheaded stepchild. plus, I more or less neglect to oil it ever, and have never seen a speck of rust.
also, interestingly enough, I bought it the day that above pic was taken in Chicago. it was in my pocket at the time....
