As I had pointed earlier, going back to the Endura or the Delica (no choil, lockback, steel spacer) is like going vintage in a beautiful way. Those are the roots of modern “tactical” folders: “one hand opening and closing” and “Clip-it”. The Endura I have bought from the Knifecenter is just flawless: zero blade play. It’s a great perfectionist work from Seki knifemakers but lockwise it was not the case with my Delica: it has a noticed vertical play while cutting hard things.
The results on wood cutting were top-of-the-notch despite that annoying recoil of the lock on each hard cut.
I have been looking on the internet and the forums and someone mention to tight the screws. Why not ?
I have found those torx screws were not tied and I could easily adjust them in an half of a turn clockwise.
The lock screw was also easy to turn and now I don’t have that annoying vertical play anymore. Hurrah !!
Here is my solution: the handle screws need half a turn. I have done it on my Stretch and it is also now perfect.
Before when only bolts were used in knife construction it was not possible… But with the Delica 4 all screws construction it’s easy to adjust them.
The action is a little more stiff but no more recoil while cutting hard things like wood or plastic.
I’ve also had luck lightly sanding the lockbar until it fits tighter in the notch on the blade. You have to take the knife apart, and go very, very slowly, but it’s another avenue in case tightening the screws doesn’t work.
