More adventures with this knife. I have probably opened and closed the blade back and forth thru its first inch of travel a thousand times or better, and it has continued to improve as far as being able to open it one-handed. This is the only knife I have ever had to do that with but so far I'm saying it was worth it.
The knife came to me with the clip attached blade tip up and pointing right. I normally carry my clip pocket knives in the left hand corner of my left front pants pocket where it is most out of my way. I looked at this knife as I kept working the blade to make it open easier and I thought, hmmm, you know if that blade came open in my pocket and I reached in the pocket, I could end up with a hundred stitcher in my hand. But I didn't have a wrench handy to swap ends so I put it out of my head. I was going to visit a friend and I thought I'll just tuck this knife in my pocket to see how it carries. Two hours later I was standing at the sink running water over my pinkie knuckle while my friend dug out some first aid supplies. I have never ever had a knife come open in my pocket like that. I've carried my work knife tip up like that for years but it has a strong spring holding it shut. Live and learn. I shudda listened to myself.
So the next day I decided to move the clip to the other end, which not only puts the tip down, but puts the blade against the left side of my pocket where I carry it. I'm thinking I'm giving new meaning to the word "fool-proof" but I'm not done yet. The clip is held on with two small Torx screws which were in pretty tight and had Loctite or some such in the threads. So I put a little drop of Permatex Blue in each hole at the other end and fastened the clip back down after I figured out that you had to push the screw into the Torx bit to hold it while you worked it thru the little holes in the clip.
Worked great, clip was still too strong, but one thing at a time. There was now no conceivable way I could draw more blood in my pocket so I went back to working the blade back and forth two-handed to loosen it up more. Strangely enough it slowly started to get tighter. Hmmm. I worked it some more and the more I worked it, the tighter it seemed to get. Hmmmm. Finally it dawned on me that the screw holes I had put a drop of thread tightener in went all the way thru the frame and ended up right on the pivot. Back to my shop.
Strangely enough, this is the first knife I have ever had to take apart. I had visions of when I was a kid and took my New Departure bicycle brake apart for the first time and all the discs and pieces fell out on the floor. As it turned out it was simple enough. There are two screws holding the whole knife together, the pivot screw and one at the other end. With those out a little judicious wiggling and prying with a screwdriver lifted the whole frame side off the big pin that acts as a stop for the blade when it closes. There were no springs, no bearings, no little parts, just the blade slipped over the pivot post with a thin washer which appeared to be made out of brass on each side. This is truly a minimalist knife in its design, very impressive.
And yes, there was a film of drying thread locker on one of the washers. Some scrubbing with an alcohol soaked cotton swab took care of that. Now when this knife had been giving me so much trouble out of the box, I had resorted to oil to loosen things up. Several applications as it turned out. It would seem to help for a bit and then go back to resisting me. Looking at this simple pivot design it seemed to me that it would probably work better without oil, at least while it was being broken in, and that oil might just pull in a bunch of dirt and whatever else it could attract. So I cleaned up the whole pivot area with the alcohol as best I could and put it back together. Worked better than ever.
In tightening the pivot screw I determined that it was adjustable. Making many micro adjustments I found a place that was probably even tighter than out of the box but I could still work it with my thumb and I thought it would break in even better as long as I could move it. Those brass washers are surely not as hard as ZDP-189. In taking it apart I had discovered that what was holding it closed and resisting the initial opening was a tiny little ball embedded in the end of the frame lock which fits into a corresponding tiny hole in the blade when it is fully closed. You can see the other end of the hole that holds the ball in the end of the frame lock next to the pivot. I don't know if it rotates like the ball in a ball point pen or is fixed. Somehow knowing what I was overcoming when I pushed on the thumb stud made it easier to work the knife.
So today the knife has been much friendlier to me. It's a keeper, tho I think I had determined that when I put it in my pocket knowing it would be getting its first scratch. I could loosen up the pivot pin a smidgeon to make it look more like the videos when I open it but I think it will wear in better this way. If I was in close quarters and needed to cut something, I could open it one-handed today. It still isn't pure fun but I can already tell that this knife is going to keep on growing on me and will probably end up being my favorite knife. I'm sorry I missed out on its big brother tho this one might be the best compromise if you had to end up with just one knife. But dang, my thumb still hurts.
