I did not watch the video, but there is a sneaky trick for getting the back lock into place which I assume is shown in the vid. If you don't do it right, its darn near impossible to get the knife back together. But if you know the trick, its a piece of cake to get the back lock reinstalled. I learned the hard way.
I have not swapped scales on Enduras, but I did it with Delicas in order to get a black FFG. The secondary result was the world's only known blue Delica SE.
