He's thinking jdavis882, who said many questionable things, many seemingly untrue, and disappeared after some questionable dealings.
Elmax is fine. The supposed problem was that zero tolerance had a bad heat treat and the blades underperformed. Which apparently they did have a short run of bad blades. But jdavis882 made such a big deal about it now everyone thinks zero tolerance has terrible heat treats of all their steels. Mine work fine, so do many others. Sure there are some bad ones it happens in production knives, even to spyderco at times.
Jdavis882 also said you could change the lockup of a Chris reeve by forcing the scales... Lol
