Autonomy Spring Replacement Kit Review, takedown and button wear update

#1

Post by Evil D »

I've only had this knife apart one time in 5 years, so I figured it was due for a thorough cleaning and inspection. I've been wondering about the button wear concern ever since seeing this thread viewtopic.php?f=7&t=87181#p1437909

Also to be clear, I did not do all this because my spring failed...so while I did want to do a bit of a review on the spring kit, it was only out of curiosity and not necessity, I reinstalled my original factory spring and mostly just wanted to show what the kit came with.

Image

The main components of the kit are two replacement springs, a torx wrench, and a spring compression key/tool. You also get some thread locker and a cool edge protector sleeve thing since this spring can be replaced without taking the knife apart and you need to do so with the blade open, so it's a cool addition that Spyderco adds to help keep you safe while you're working. I like this WAY more than I thought I would, it's effective and faster and easier than painter's tape.

Image
Image

Something of note, the Torx wrench only fits the pivot screws, and is not enough to fully take the knife apart. In full you'll need a T10 for the pivot screws, a T8 for the scale/body screws and clip screw, and then a T6 for two small screws on the back side of the scales near the pivot. These two small screws help to keep the scale held down around the pivot because unlike most knives there isn't a back side pivot screw that presses into the scale/liner to hold everything together.

Image

Lastly they offer up some instructions for replacing the spring. This is a pretty unique bit of Spyderco Edge-U-Cation, I'm not aware of any other paperwork that offers actual instructions for taking apart and reassembling any Spyderco product. Given the old "disassembly voids your warranty" policy it's a pretty unusual piece of Spyderco history.

Image
Image

As for servicing just the spring, it's very simple to do. It's no surprise that Spyderco won a Blade Show award for this design, it's pretty brilliant when you compare it to how complex other automatics are.

Image


Anyway, here it is taken apart, all except for the scales of course. I've rinsed this knife out and cleaned it with Q-tips but this is the remaining crud from 5 years of carry and use.

Image



Alright, on to the button wear issue.


Or in my case, the lack thereof. The button does show some wear, but I would see it more as "break-in wear" than "wearing out". This first pic shows the button as I pulled it out before wiping it off. I don't think any of this is metal dust and is more pocket lint, but again I've rinsed this knife out a hundred times over the years so if there ever was any metal dust it surely got washed out by now.

Image

And here it is wiped off.

My first thought was that maybe the button on the DLC version is coated in DLC, and that helped to slow down or reduce wear. On the other hand, I have my suspicion that the hardware on these knives is coated in something lesser quality than actual DLC, because the edges of my scales are showing a lot of scratches and wear while the blade has been through **** and barely shows a scratch. I could see them using a less expensive coating to save cost on parts that won't see the kind of wear and abuse that a blade will see. On the other hand, DLC is apparently harder than steel, so it would make sense that coating the button would slow down wear, wouldn't it?



Getting this knife back together is an exercise in finger gymnastics. There are so many pieces that need to be in their place before you sandwich it all together, one of the more frustrating parts is the stop pin that wants to fall out and get lost. I added a little dab of grease to help hold it in place and that helped. I didn't take any pics of the reassembly because I misplaced my third hand, but the basic steps I took are:

1. Assemble the front scale, including the pivot bushing and washer.

2. Set the stop pin and lanyard tube in place on the front side scale.

3. Slip the fire button into the front side scale from the bottom/front, and put the blade onto the pivot. The button must be aligned so that the spot that it locks onto the blade is in the right position.

4. You can half way assemble the back side scale/liner, but only put the two small screws up by the pivot in. The two body screws will be later once you have it all sandwiched together.

5. Taking the front side scale in your left hand (or right if you're a lefty), and the back side scale in your other hand, you need to first slip the fire button spring bar into the fire button before sandwiching everything together. There's only one right way to do this so make sure you get it right. You could potentially flip the fire button around 180 degrees but it won't fire or lock correctly so pay attention to how the button is rotated and slip the spring through the little hole in the botton.

6. With the spring bar in place in the fire button, work on lining up the fire button and lanyard tube into their holes on the back side liner. This is the most tedious part because so many things need lined up correctly before it'll sandwich together, and you'll be working against the spring bar tension too. Once the fire button and lanyard tubes are in place in the back side liner holes, you should be clear to smoosh it together, and then you can put one of the back side body screws in place and that will hold it all together. Once you're sure everything is together correctly, put the last body screw in and you're almost finished.

7. Lastly you need to put the spring back together and assemble the back side of the pivot cap. Of note here, this knife only uses one washer, which really freaked me out because I was sure I lost one but the back side of the blade actually rides on the inside rim of the pivot cap that covers the spring. I added some grease to that surface for good measure. If you just follow the instructions on assembling the spring, it's very simple. The first time I did this, I didn't have the spring compressor key thing and I just used my thumb to press and turn the cap and get it seated. It's a little weird but once you figure it out it's quite simple. Again, very ingenious design.


Lastly, just wanted to show this thicc boy pivot bushing. I know a Military/Para 2 pivot are on the larger side but I don't know if they're this big.

Image

And here she is all clean and greased and wiped down with some Tuf-Glide for good measure.

Image

This spring kit is currently listed as out of stock, hopefully it's not discontinued. If you're at all interested in these knives I would highly recommend picking up a couple of these kits. Little bits like this tend to be hard to find used 20 years after they're discontinued.

Really nice writeup. Maybe worthy of a sticky.

That final pic is about as good an advertisement for Spyderco's DLC as possible.

Great piece of information, thank you for taking the time with your presentation. I have to agree , I really feel this needs a stickie so anyone can find and resource information in a timely manner . I’m very impressed how this auto is constructed and how Spyderco took the steps to keep the knife operating. Definitely not a use , abuse , break , and throw away knife . All, I can add is I definitely want one one in the future . Dan

Thumbs up on the stickie suggestion. I'm years away from needing to replace the spring (bought the kit anyway) and will want to find this thread when the time comes.

Hey, Evil D:

Great write up--thank you for sharing!

As the guy who wrote the instructions and took all the photos for them, I'd like to clarify that their intent was only to guide you through the process of replacing the spring. Similarly, the spring replacement kit was structured only for that reason. It is not a "complete disassembly" kit. Also, disassembling your knife does not void the warranty. That policy was revised several years ago. Reassembling a knife in a way that might compromise its proper function and therefore cause undue wear on the parts is another matter.

When Kristi and I visited the Coast Guard training center and discussed their needs, they explained that they were using other brands of automatic knives and had to completely disassemble and reassemble them every time they did a salt-water op. They wanted something devoid of internal cavities that could be fresh-water rinsed and blown dry without disassembly. They also wanted to be able to replace the kick spring without complete disassembly. The Autonomy design achieved all that and the spring replacement kit supports those goals within their defined parameters.

Stay safe,

Mike

I thought I'd as this here instead of making a whole new topic, but does anybody know when the kits are going to be in stock or where they might be available?

I've wondered this, too. My experience is that while several places "carry" them, they're never available. I've been looking for months.

Seems most of the Autonomy stuff is OOS, I'd bet this is a lower priority model and parts for Spyderco as compared to a Para 2 or Native 5 etc. I'm still watching for an orange Autonomy 1.

Excellent write up David. I guess I should look for a kit to stash away if, or when I need it.

They've gotten hard to find, have been out of stock for a while now. I can't imagine they're discontinued since both knives are still in production. I plan to grab a few kits when they're available again.

Sounds like a good plan.
Yup, I can't find the kit as well. ☹️
I'll send a post here if I happen to run across any.

Does anyone know if this is an industry standard type spring, or a custom design for Spyderco?

On another note, if Spyderco cannot produce them, why not let Wolff or one of the other spring makers produce them?

Springs are a real booger to make and my guess is that Syderco has them made by another company.
