Inside the large Manix--Pics

I see rounded corners and edges on that lock also.

I agree that the front of the "tenon" part is rounded but that doesn't take the lock pressure so I'm sure it matters. The rear part (a little lint in the picture) is not rounded that I can tell. But the fit is sure off.

bladeprince I would be interested in seeing the video.


Sal,
In the pics the lock bar does not fully seat in the blade lock well. Is full seating necessary for rated strength?

Hi Bors,

Without going into a lot of detail, you really don't want the lock fully seated for a variety of reasons. The first and most obvious is that anything, lint, etc. will immediatly begin to lift the hammer. A little "cushion" is nice. When a lockbar begins to move, it is not an "up & down" motion, it is following an arc around the lock pivot. This changes the geometry of the interface between the tang and lock hammer, and changes the response to force.

Very interesting point Sal. I always thought the little rounded cut out from the laser at the bottom of the blade slot for the lock bar acted somewhat as an area that would provide cushion and a place to compact some of the pocket gunk as you said. I also figured being that most of these knives were pocket clip carry type folders that you purposely seated the locks deeper on these bigger knives like the one I show a pic of above because pocket lint was not as much of a problem for clip carry knives as it is for the ones that roll around in deep carry with the car keys. I've seen them both ways and all points in between in the industry though so I guess there is an ideal and you shoot for that but don't always hit it dead on.

Hi STR,

In our industry, locks evolve. Look at the Walker linerlock, over the years and all of the mods from Vince Ford's offset hook to Chris Reeve Integral. Angles and geometries have changed on tangs and liners. Opinions are still in disagreement stages.

We're constantly studying and evolving our locks and each offers its own challenges.

The kind of forces that modern knife buyers expect from knife companies from their "locks" in harnessing such a sharp cutting tool is increasing. Good locks are important.

I might also add that "slip-joints" maybe part of the future because of legislation and fear.

Hello Sal,

Do you agree that my lock machining has a problem? Could this possibly be one of the defective ones you talked about? Please my video and pictures on post #40.

Thank you

Boy is that right. I made up an integral lock quiz a while back that didn't go over so well with some makers. Many refused to take it because they found out their buddies that they thought were on the same page they were on answered differently. Some got angry, some took it and laughed and others shrugged it off and still others just never got back to me at all. I didn't make it up acting like I know the answers or because I was trying to be the professor or anything. I thought if we could get enough consistancy that I could improve my own knives but in the end the answers and opinions on which way to make an intergral locking knife were as varied as the knives themselves. I suspect that as with anything nothing is really written in stone. We have to learn to grow and change with the advances we make in technolgy and from tests and accept that sometimes what worked in the past may not work now as new info becomes available. Changing old habits dies very hard though.

Does anyone have pics of the Chinook I's innards?

It was supposed to have a very tight, strong spring/lock mechanism.

For people that want to maximize their lock strength on their Manix/Chinook's maybe their spring could be substituted for the biggest, strongest one possible (like the Chinook I's). I don't know if a custom maker coulkd do that, or if they could be sent to Sal (for a fee), or if you could rig it yourself...

This wouldn't be for everyone, you might have to use a second hand to disengage, or hit the gym more often!

Personally, I'd go for that, and I'm sure the hard use/SD crowd would dig it too.

Thanks Sal,
I suspected that it was part of the design.

Does this mean that there may be some slipjoints in Spyderco's future?

Hmm ... I wonder what that would look like ... maybe something like this?

Hi Prince,

Couldn't open the video and couldn't tell from the pic.

Please send it in and we can check it out. Send a copyof the video if you can.

Thank you. I will. The video is on one of those sites like "YouTube". Maybe it was down. I tried the link and it worked fine for me. Anyway, I will send them both via email and include a letter to refererence the email. You may wish to try the link again, if you are curious, but I'm sure you have more on your mind.

One more question, is there something about knife legislation that we should know about? Is anything being done to prevent it? I can't imagine that the number of "knife crimes" are up just because more people care around a locking folder. I'd even bet that muggings and some attacks are ever down.

Hi Prince,

Probably me and not the site. I 'll look for the piece. Regardless of what's wrong with it, we'll make sure you get taken care of.

Thanx for taking the time.

On the slip-joints, no new legislation. At least not here yet. I'm seeing it appear more often overseas over the past 3 years and I think it might spread.

Bladeprince I was not suggesting that the rounded corners were the specific areas responsible for your lock defeats. Just noting it really, that if you can see immediate evidence from a pic like that of rounded edges that it is probably going to have other areas worth looking at also to find out how and why those rounde off areas got that way and what the rest of the parts look like where the camera doesn't show. Worth a deeper look in other words.

Understand. Thanks for the observation and input. Appreciated.
