Easy Chaparral lock-bar fix...

I bought a Raffir Noble (veteran) and could NOT operate the lock without EXTREME trouble. I got a RMA from Spyderco and was going to send it back, but I love the knife's thin blade and scales so much that I couldn't do it.

I read Sal's recent post where some fellow had moved the spring forward so I decided to do that also. Was really quite an easy fix, although I "seldom" take a knife apart. Just takes a T6 and a T8 and you're good to go. There is no Lock-tite, thankfully, and it's easy.

BTW, it's just as easy to reassemble, although obviously the warranty is now up in smoke. I'm not worried about that, as I've never needed warranty work for a Spyderco, and I've carried them for the last forty yrs or so.

Just tape the blade edge or keep some BandAids on hand. I nicked myself three times without knowing it, until I saw the blood flowing. Very unusual for me, as I sharpen a lot of knives...
What a WONDERFULLY SHARP BLADE!

I removed the scales, the steel liners and blade, as well as the lock-bar.

The first pic is the "standard" position of the spring, slid all the way to the right in its channel.

So, I removed the lock-bar and slid the spring way forward to the left. This really worked great until I tried to close the knife...and it wouldn't. The blade would hit the spring tip and wouldn't fully close, as per the second pic.

So, I slid the spring back a tiny bit to get the spring's tip out of the way of the blade, and it works like a champ. (pics 3 and 4) The spring is under constant pressure, so it will NOT move around under normal use.

Pic 5 shows the present location of the spring in its channel, having been moved to the "left" 0.273"...about 1/4 inch is fine.

The last pic (6) shows the blade at the "break" point...where the blade is first unlocked.

The spring pressure to release the lock is just fine now. It is still a very solid snap and lockup, but a pleasure to operate. I think this is a very easy "fix" and doesn't require any mods of the spring. But I'm completely happy just backing off the spring enough so that the blade closes freely.

Good post, I'm sure it'll help many out there.

I don't have an issue with mine, the only issue I have is the clip. It bends too easy and I've never had the issue on any of my wire clipped Spydercos. It's by far my favorite stock clip. Also, the recesses in the scale aren't deep enough to properly seat the clip and it has starting to become loose quite often.
 
I'm really glad that you were able to fix it, i can tell from watching videos that some of those chapparals are really stout.

That is a fantastic looking scale pattern.
 
Nice workaround Sonny...but do you think the spring is gonna "walk" it's way back to it's original position?
 
Do you think this would really void the warranty? I mean disassembly is now covered under warranty and you haven’t modified any parts.

If it does walk back in, you could always make a spacer to inset in that cavity.
 
Or just bend the spring slightly to reduce the spring tension.
 
Petey.....
The spring is under constant tension, and I couldn't even push the spring at all toward the "stock" position, although I tried to using a long-nose pliers... You have to remove the lock-bar to move that spring...I've operated my Chappie quite a few times now...maybe 40, and it's just perfect...
In the unlikely circumstance that the spring could "walk" back toward factory position, it would be simple to just drop a 1/4" metal or plastic spacer in the "void" position on the far right of the channel...positive cure.

I was not aware that disassembly is now covered by wtty. Thx for that info...
 
I recently got an FRN Chappy, and working it with a bic pen a few hundred times and leaving it half open overnight completely fixed the stiffness without opening it up. It’s very easy to close now.
By the way, it is a great knife. The edge on that thing from the factory was phenomenal. Taichung Spyderco factory workers know what they are doing.
 
Hi Donald,

Sorry I didn't get back to you on your email, running behind. You might consider posting this on our Spyderco.com forum for additional discussion?

Thanks, Sal...I really like this Chappie... This must be what folks call "scary" sharp. It certainly
managed to draw some of my blood...3 times...and I never felt a thing...
It's a pleasure to hear from you, Sal.
