I'm not familiar with them since production moved from Camillus to Ka Bar.
However all of Ethan's designs, when they were made by Becker Knife & Tool, and including those made by Camillus were great, utilitarian knives. I've owned a handfull over the years and the Combat Utility is my favorite. The original Necker is probably the least used.
BladeForums generally seems to speak well of them and several have been fairly extensively tested.
Little known fact about Ethan Becker, he and his mother wrote the classic "Joy of Cooking."
