The Tanner gun/knife show's in town this weekend. I spotted two knives of interest yesterday and went back today to do some swapping and trading, successfully acquiring both. One was a Spydie CTS Mili and the other an Ion Fusion 110. I came home and did some testing: The Mili was, as expected, laser sharp. The Buck was sharp but rather rough. It is like new and never sharpened but hung up cutting through paper and pulled tufts of paper out of cardboard. I had researched both knives on line last night and saw an old post by Joe Houser about the Ion Fusion actually getting sharper with use due to the weaker metal wearing away leaving a sharp edge of the coating material. I decided to give it a try. I cut a large flap off a cardboard box and proceeded to slice and dice, making long cuts using the whole edge. Like magic the cutting got easier and easier as I went. After thirty or forty cuts I went back to paper and wowie zowie it slipped through like butter.
