The Strongest lock?

HellHound · #1

Hey guys, so I was thinking what lock could take the most abuse before cracking down, like batoning and spine wacking and other abusive use, between a liner lock (military), compression lock(para1 or 2) and caged ball(manix2)?
Rank them from the most to least resistent. If there was a thread like this before then I would really want to see the opinions and results. Thanks for your thoughts guys.

Relevant quote from Sal:

sal wrote:Hi Poodle,

We've gotten to the point where we can make most locks as strong as we plan for. The Lockback as seen on the Chinook (Manix & 83mm), the ball bearing, Compression and the new Stop-lock can be built into the Very Heavy Duty (MBC - 200 inch/lbs per inch of blade length) range. We select materials and dimentions to meet the requirement we sedt for the model.

We've not been able to get Walker linerlocks or "framelocks" into that range due to the long spring.......yet. But we're still developing.

I think most locks can be made to be strong and reliable if the manufacturer extends the effort.

Also, for Batoning, you can basically do it with any folder (not that you would want to), but I would just do it with it unlocked.

What Jossta said/quoted. The same kind of lock can vary from model to model, as it can be beefed up a lot. For example, a lockback on the Chinook is much stronger than a lockback on a Dragonfly 2. The best lock for abuse is no lock at all. Fixed blades will stand up to batoning, spine-whacking, and other abuse much better.

Honestly not a big fan of the ball bearing lock, I'd probably put the compression and lockback at the top of the heap. Don't know anything about the new Stop-lock.

Surely opinions will vary greatly on this, but I doubt most of us are even qualified to have an opinion (including me) as we're not engineers nor have we ever done any real world testing to the point of failure.

of the three choices, I would put the military as probably the weakest of the three (and it isn't a weak lock) then I would maybe give the smallest ever edge to the compression lock on the para2, but would probably take the manix 2 for harder use.

jossta · #6

Yeah, I think the comp lock gets the edge of the 3, but I wouldn't use my Para as hard as I would a Manix just b/c of the blade shape/tip. For harder use in a comp lock, I would go for the Super Leaf.

Where does the lock on the endura 4 stand?

jossta · #8

Endura is "Heavy Duty" which is (I think) one level below MBC. This is probably where the Military stands. I think the Manix and the Para are both MBC which is 200lbs/inch. Not sure what the rating of heavy duty is.

I have never broke any lock,on any knife I've ever owned. So i would say any spyderco lock will hold the blade open.

HellHound · #10

In general think the contest would be between the manix and para,I just need a lock that could handle extreme use if needed in an urban or an wilderness environment if the need should arise, not very likely but you never know.

jossta · #11

Honestly, if you can carry a 4" knife, I would go with Military, especially for the wilderness environment. I really doubt the lock will fail. Otherwise, Superleaf, Para and Manix are all good options.

Other option is to find a second hand C95 Manix. That thing will do everything you ever wanted and more. Only thing I don't like about lockbacks is that they're harder to clean.

I really really really really really really really really wish they would do a sprint of the C95. I would buy it in any steel, but in 3v or Elmax I would be in heaven.

Like. :D

I'd take a C95 in just about any steel!! Especially an XL C95...

Does that make 2 things we agree on :p ?

Why is lock strength always such an issue? When cutting, force is being applied opposite of the direction the lock is holding the blade open to. To me it seems the only way the lock would fail ever is if you apply force down from the spine of the blade. Is there something I'm missing here?

araneae · #16

I love these types of speculation threads. I tend to keep my urban batoning to a real minimum so I'll sit this one out. Sal's quote in the 2nd post pretty much says it all.

Who knows, i'm kind of lost when it comes to this stuff. If I somehow break my folder's lock it means I wasn't using the right tool for the task at hand, and probably deserved to cut myself.

though to answer the original poster's question (and purely on speculation), i'd have to rate them Comp. lock, liner lock, then CBBL.

Hmmm I dunno, do we agree that we agree on two things? :p

TBob · #19

Sal said it best. Personally, I've never broken or compromised the lock on any knife in my entire life, not even the cheapest ones I had decades ago as a teen. Therefore, I'm not the least bit concerned with any Spyderco's lock strength.

the liner lock would fail almost instantly, the manix 2 lock also

don't know about the compression lock, it might last a bit longer

a strong lockback might withstand batoning and spine whacking etc but not the locks you asked about no way
