Re: Something I do not understand about the Chaparral
I'd like to thank everyone on this thread, especially Sharp Guy & cptdean. I purchased a new Chaparral Raffir Noble two days ago and was ready to pull the plug and send it back to Knife Center. The pivot was pretty stiff, but I knew I could fix that with some KPL and maybe some pivot screw adjustment. However, the stiffness of the back lock was awful and I was unsure how to fix it. Cptdean's pictures made me feel confident about opening the knife up.
Now I can actually start to enjoy this gorgeous knife (BTW - if you've not seen the Raffir Noble scales in person, it is hard to appreciate how cool they are). Moving the spring as far toward the pivot as I could without hitting the blade made this bear into a bunny. I also put a little KPL on the sides of the lock pawl that contact the frame liners. This won't ever be the blade dropping fidget machine my PM2 is, but this is a knife I intended to EDC in slacks for work. Nobody wants to see me fidgeting with my knife at work. I'll leave that burden to my family.

Re: Something I do not understand about the Chaparral
Recently acquired a Chap in CF the lockbar was very stiff and uncomfortable to disengage. Dissembled the knife and slid the lockbar spring slightly forward (about 1/8"), fixed the problem.
Thx to Sharp Guy & cptdean for the fix!

Re: Something I do not understand about the Chaparral
I’ve done this to a couple of mine and it t works a treat. What I don’t understand is that after all this time why Spyderco doesn’t do a CQI and fix this easily fixed issue?

Re: Something I do not understand about the Chaparral
The lock bar on my Chap lw was very stiff out of the box, but after a break in period it basically feels ideal to me now.
I'm curious if anyone who has done the manual lock spring adjustment had it become too soft over time and ended up moving it back? Guess it's possible that mine "broke in" by slowly shifting itself forward over time somehow, but that seems a little unlikely and I've never opened it up to look.

Re: Something I do not understand about the Chaparral
Over time they tend to loosen up/break in. I was going to attempt the fix, but then I bought another one from a local shop that was the last one on display. It was much softer and easier to manipulate the backlock. The shop had not adjusted it, it was simply open and closed a lot. Some folks simply leave it partially open overnight or longer, which works as well.
I also started using the inside edge of my thumb below the nail around the edge of the first joint, instead of the end/tip to operate the bar. This really helped, and not just with the chaparral.

Re: Something I do not understand about the Chaparral
I don't find my Chaps stiff at all. I have never felt the need to adjust them.
Re: Something I do not understand about the Chaparral
No noticeable change in either of my Chaps. Given the properties of spring steel I don't expect any change, at least not from the springNate wrote: ↑Sun Jul 12, 2020 6:46 amThe lock bar on my Chap lw was very stiff out of the box, but after a break in period it basically feels ideal to me now.

Re: Something I do not understand about the Chaparral
Yeah this doesn't actually work. If it did then they're not using very good steel for the springs and they'd all be getting weaker over time. Eventually, people would be complaining the springs are too weak. People say leaving the blade half open will help loosen the spring on the Manix 2s as well. I left one open on my desk for several days. No change

Re: Something I do not understand about the Chaparral
Springs need to break in or settle in, sometimes. If you have ever dealt with certain oem magazines for firearms, they are very stiff feeling and very difficult to fully load initially. After cycling a few times or being left loaded for a while, they become easier to fill to capacity. Someone much more knowledgeable than I can probably explain the specifics better than I could attempt, but it is a truth/reality in functioning.Sharp Guy wrote: ↑Sun Jul 12, 2020 8:57 amYeah this doesn't actually work.

The chaparral back lock is narrow and not contoured as much as wider locks. It has more focused points of contact which can be uncomfortable. I almost gave up on the chaparral, but after swapping point of contact on my thumb, and simply using it more, I could not be happier. I like the initial stiff spring, actually, as I pocket carry with no clip and do not want it to become loose enough for any surprise openings in the pocket.
Re: Something I do not understand about the Chaparral
I don't understand something different about the Chaparral. Why don't they offer it with more scale options? Like a traditional knife that comes in different bones and woods. The Chaparral has been out for several years and there still isn't a version that I really like. Doesn't seem like it should take years to offer it in a stabilized wood or a stable wood like african blackwood or rosewood. Or burlap micarta, or polished G-10...
The upcoming version is interesting but a bit polarizing I think. Not a fan.

Re: Something I do not understand about the Chaparral
Yeah, the offerings to date haven't really been my thing, either. The raffir noble looks beautiful, but I'm not big on smooth scales on folders. The frn appealed to me most of them all, and I'm definitely interested in the sun and moon g10. But I agree, wooden scales (i love the look of ironwood, walnut, cocobolo) or micarta would be great so long as theyre not polished super slick. I'm sure a lot of people would like bone/horn, too, although I'm not one of them.ABX2011 wrote: ↑Sun Jul 12, 2020 10:50 amI don't understand something different about the Chaparral.

Re: Something I do not understand about the Chaparral
Thanks but you're not telling me anything I've not already considered. I've been around firearms for 55+ years. Yes, springs can change through use over time, especially coil springs made of thin wire. It's not something that usually happens over night though. If it does they're not made of very good spring steel. I'm sure a lot has to do with the application too. The flat spring in the Chap is fairly stout and not likely to have a noticeable change through normal use (IMO). I had my CF Chap for several months and the thin lock bar continued to be difficult to depress. It was also a little gritty when opening. So I decided to open it to clean it up. By accident I didn't seat the lock spring all the way in the slot when I reassembled. I noticed a big difference in the tension on the lock bar. It's been that way for almost 4 years. There's still plenty of spring tension on the lock bar and I challenge anyone to try to shake the blade out. The coil springs in the CBBL locks on my Manix 2s are still strong even though some have been opened and closed many times. What's changed is me. I learned to hold the knife to make it easier to open. My fingers are probably a little tougher now too. Maybe I could've become used to the thin lock bar on the Chaps eventually but decided not to deal with it when I bought a Chap LW.Tgmr05 wrote: ↑Sun Jul 12, 2020 10:29 amSprings need to break in or settle in, sometimes.

Re: Something I do not understand about the Chaparral
While the first is a CQI procedure, the second is wishful thinking. If you’ve seen the THICK spring and the right channel it lives in, you would think otherwise than Sal’s, “the lock softened as it broke in.”

Re: Something I do not understand about the Chaparral
I would be willing to bet that Sal's statement is based on research performed in their lab. There's probably a machine that repetitively depresses the lockbar that also measures and records the pressure required to overcome the spring. I'm sure it softens over time. Everything wears out.MichaelScott wrote: ↑Sun Jul 12, 2020 4:01 pmWhile the first is a CQI procedure, the second is wishful thinking.

Re: Something I do not understand about the Chaparral
What constitutes “time” is the rub. I doubt if a human could stress that spring (really a thick steel bar) enough in a lifetime to wear it out, or in.SSD_777 wrote: ↑Sun Jul 12, 2020 4:17 pmI would be willing to bet that Sal's statement is based on research performed in their lab.

Re: Something I do not understand about the Chaparral
I thought XHP was quite rust resistant based on my experience with a FRN Chaparral that very frequently was my secondary EDC for quite some time... but earlier this year I purchased a "new" G10 Manix2 w/XHP off the secondary market that was very much a used knife -- it had a bunch of rust starting on the thumb-ramp working it's way all the way down and around the pivot, and needless to say the liners were very rusted as well... I cleaned all of it up with bar keepers friend and wiped the liners down with a silicone gun cloth, put a dot of nano oil on each side of the pivot, and then wiped the blade down with a very thin coating of mineral oil (I treat all my tool steels the exact same way) and I have had zero issues since then...Sjucaveman wrote: ↑Tue Aug 07, 2018 9:30 amI like my raffir noble chap but my frn model the clip grooves were too shallow and the clip broke the frn so it no longer stays in place. I've also found xhp to not be rust resistant enough for my sweaty pockets.
TDLR: Treat XHP as a tool steel and it should give you zero troubles.

Re: Something I do not understand about the Chaparral
The spring is exercised everytime the lock is disengaged, during the entire rotation of the blade opening process and it's also under constant pressure to keep the blade closed. It's going to weaken with everyday use.MichaelScott wrote: ↑Tue Jul 14, 2020 1:07 pmWhat constitutes “time” is the rub.

Repetitive bending force on a piece of metal causes it to weaken over time, due to the development of micro cracks.
You would probably never be able to actually fatigue it enough, under normal use, for it to actually seperate. But it will, most certainly, become weaker and easier to flex over time.
It has nothing to do with the lockbar rubbing on the spring. That's a different kind of wear.
