The only thing i could imagine i discovered when i took apart my endura 4 today. Well 2 things. First the liners werent as beefy as i would have hoped, they would bend a little if i squeezed on the handle.
What concerned my more is that there doesnt seem to be much metal around the hole where the blade is bolted to the handle. In all honesty it seemed like there was only about 1/8 of an inch of metal surrounding the bolt hole in two places.
Dont get me wrong, this is a good knife, I carry it in my bullet proof vest as a backup item. However I just expected, and prefer, it to be a little bit beefier and solid.
For example when i got a caly for my grilfriend the liners were thicker and stronger and full sized and it did not give when squeezed.
But it is a great knife, I love it, dont regret buying it. It just wouldnt me my first choice for a work folder.
