I am a much in the "a big knife can do everything a small knife can, but a small knife can´t do everything a big knife can" - camp.
For me the Endura has the optimal, "regular" size for a folder, while your "mid sized knives" (Delica, Para 3, Native) for me really are small (as small as I would go actually concerning cutting edge) and more specialized knives for days when a small carry
has priority for what ever reason...
As soon as you really use a knife, for me personally a longer blade has
- lots of advantages (for example: cutting stuff with larger diameters; much better in cutting things like cardboard, cause you can do much more of a "drawing motion" and "don´t run out of blade before you run out of material"; after a long day of cutting there will more likely still remain a sharp section on a longer blade than on a shorter and so on)
- but really no disadvantages - again, in actual use
. (It might very well have some in carry, in scaring people, legally and so on).
If I really want a "short blade", pinch gripping the knife further up on the blade is totally sufficient, or (I almost don´t dare to say it anymore on this forum
) choking up on the actual edge
is no problem at all if you know how to do it (and fortunately quite a few experienced knife users DO know how, and I personally use that choking up on the edge all the time)
So: From a purely practical point of view I personally have no reason to carry a rather "bulky" package with just a short edge and fat blade (like the Para 3) over a slim carry with lots of edge and a thinner, slicey blade (like the Endura).
