WOFT,
I've carried an Endura daily for about 2 years now and love it.
In terms of strength I would not rate it at the top due to the small pivot. I don't use mine as a wilderness blade. I carry mine mainly in an urban setting for defense. At this it excells. The Endura carries with it's pivot down in the pocket. On the draw it is in a natural position to open quickly.
It holds an edge very well and can easily be brought back to a shaving edge with a hard stone and a strop. It is also a lightweight knife that is comfortable to carry. I love the Endura, plain edge.
For wilderness duty I use a drop point S&W SWAT with G-10 scales. I'd put this knife up against any more expensive folder. Mac
