It does seem frustrating, especially when you consider how small and cheap the parts would be (comparatively). I feel like it'd be better to either standardize everything (always a good idea because then you need less parts overall) or to bite the bullet and spend a few hundred dollars to carry the spare parts. I'm not sure why their policy is this way, I can only think that either the workers in Golden aren't familiar with other knives or that they don't have the parts to fix the knives. The former doesn't seem likely and the latter seems like a simple fix.
Totally understandable re: customs.
Is the noise/feel a narrow grind or is it a flatter grinding? Does it help to back off the pivot a smidgen?
When you first took the knife apart, how did the washers look? Anything bent or dirty?
The new lock rock sounds weird too. Maybe try rotating the stop pin so it is facing the "fatter" side (if any) to the tang.

The noise was narrow, coming from the detent ball. This was confirmed by lifting the detent ball slightly off the blade tang to actuate the knife, which it did so silently. Also, when inspecting the washers they looked perfect and polished. As for rotating the stop pin, it is actually self adjusting and rotates freely, which is how I first noticed the lock rock when I applied negative pressure to the blade and was able to rotate the stop pin with my finger!
I agree with your assessment that the detent ball is doing something funky. A mildly flattened ball shouldn't be a problem, unless the flat face is angled against the tang, causing a great deal of pressure/friction.
The self-rotating stop-pin is a first for me. I'll check my Techno tonight to see if it can do that too.
Not yet, what would be an effective way to reach him?
My Techno's detent is partially flattened as well. There appear to be two flats on the sphere. Everything is smooth feeling, with a slight soft grinding sound after I removed the mineral oil I had there as a lubricant.
My stop pin does not roll freely, though.

Not sure exactly, but he does frequent this forum and the Spyderco forum. Maybe there you can reach him. If you took the knife apart then your warranty is gone, but they may be able to fix for a fee.
Good luck.
Wow !!! Haven't fixed it yet ??? Too bad. Such an easy little knife to fix.
He has already tried a series of user-level fixes; coupled with cross-border shipping and a note from the warranty department that they don't have the parts to repair a Techno, it's not exactly a simple situation. Unless you have a suggestion.
- originally posted 9/6/2015, but this advice was seemingly ignored.
If the only 'flaw' in the detent ball is a flat on it's contact surface, I'll still say that it's a non-issue... but the screeching sound remains, and now the knife is described as having blade play. The screeching sound was determined to come from the detent ball contact, as when contact was broken the problem sound disappeared. So it's friction. The friction needs to be eliminated. I'd already suggested how to do this.
The tang can be polished smoother than it is out of the box. I admit, this shouldn't be necessary in most cases but this is an extenuating circumstance. The contact surface (tang) can be polished as smooth as glass. The ball running on a smooth surface, especially after opening & closing as many times as the OP has already done, shouldn't exhibit any signs of galling or noise from friction. That's how I see it.
These are production knives. They're not all finely tuned and refined by hand. Sometimes the grind is asymmetric, or the blade isn't scalpel sharp, or not perfectly centered within the frame. Sometimes there are outright flaws. QC isn't always perfect. We all know how these things can vary. Not every user can mod a knife; refine it or fine tune it and most users shouldn't have to. A knife the price of the Techno from Spyderco no less shouldn't have any of the issues described.
Some fixes are easy. Others require deeper knowledge, acquired skills, and other tools and materials. Not every enthusiast can fix a knife with seemingly simple issues let alone more serious flaws. But the answer is easy. Send it back in. Whatever the issue, Spyderco can fix it. That the knife was disassembled and the warranty remaining questionable... doesn't matter. The Techno is a simple knife. If it was flawed out of the box Spyderco will cover it. If the owner effed it up, they'll know. I would only say fix it if you can, send it in if you can't fix it, or sell it off if you can't be bothered. I understand Spyderco doesn't inventory parts from their Taiwan line, but that's not the point. If it was flawed out of the box, they'll replace. Everything else as originally described is a fitment issue and they can fix that as seemingly the owner can't, (or can't be bothered).
Ah, my apologies RobME. I remember reading that suggestion but didn't realize it was yours.
It's not my knife, but I'm wary of tang polishing just because mistakes could muck things up alignment-wise.
What about polishing the detent? I know a flattened ball is no big deal, but if the blade has since shifted (up and down play), then the flat must now be misaligned and causing greater pressure/friction.

The techno already has a very slick finish to it, being stonewashed and polished, so this would be a last resort. The knife performs great and I've since seen through the small issues it arrived with, but it would've been nice to experience the flawless techno everyone else seems to know and love haha. Though it is a production knife, I was lead to believe that spyderco's Taichung plant was capable of superior fit and finishes (which is true, my gayle bradley and sage 1 are flawless).
With my sage 1, the blade tang has a very coarse finish due to the grind lines yet has an unbelievably smooth action. Detent ball showing no signs of wear at all. This leads me to believe that the techno I received may have a defective detent ball which is much softer. Overall I would rather accept these problems than deal with ridiculous duty fees associated with sending the knife back. These may seem like knitpicks but after the gayle bradley my expectations of taichung spydies may have been too high

This works for Europe so it should be fine for US/Canada as well. Spyderco does mark it as a warranty return when shipping it back (might be wise to ask them to do so) so there should be no issues with customs.
