Military Lock question
- Thread starter YourHuckleberry
- Start date
Regarding lock strength if anybody recalls Lynn Thompson Cold Steel tests of his immediate jumping on Spyderco construction technology folder with the Voyager? line, it showed right off the bat the Spyderco Clipit and zytel lockback and lockbacks in general are a world beater for static strength load bearing tests.
The problem with liner or (same thing, just thicker) side locks are a simple engineering principal....a bent piece of metal wants to keep bending no matter what you do...the entire draw of the liner/side lock is one-hand convenience....period.
This is a more recent test and you can reasonably sub in a Spyderco for the CS product while keeping in mind the new Spyderco Delica and Endura are even stronger....
While generically you can see the problem with the other designs no matter what tweaks to material or heat treat....what is bent will collapse sooner....
This is not obviously saying the others are unsafe, but just because newfangled does not always mean better and there is a great amount of assumption out there along those lines......the last few minutes show up close shots of the knives and how they failed....

And this all is said as the owner of the Benchmade AFCK made under license to Spyderco and i believe the very first factory shot of anybody at what Emerson was doing in a small shop at that time and charging $500 back in early 90s....the Benchmade "Spyderco" was a world shaker and Spyderco themselves quickly had the Military Model out in double time....

First off, thank you all for your input and help. I'm not sure it's how I'm opening the knife that's causing it (I have large hands and deploy the blade rapidly, but not so quickly as to use the whip-cracking motion.) What u812 said makes sense: maybe it's just because it's a new knife and hasn't "broken in" just yet. Regardless, here are a couple pictures of the knife. Again, I apreciate your help.
I would be OK with that only if the lock reliably achieves that much engagement if opened very slowly/with very little force. I had a Military that would engage that far only if opened fairly briskly - not safe. I had another that would unlock with very gentle pressure on the spine (not a "spine whack" by any means, just gentle pressure) - also not safe. Lock strength and longevity come well behind reliable and safe lockup in my book - I don't need to risk unexpected unlocks and the injuries that can result.

That is TERRIBLE lockup...er...TERRIBLY GOOD lockup... 
You must be getting bored reading the same thing over and over.
Sal, CEO of Spyderco, designed this knife as if his son would be using it over in the middle East.
Sal did a fine job...I've had quite a few, and have two NIB right now.
These are both new. Note that the position of the lockbar on the tang is a big different in these two samples. Both are fine. Once you work with the knife for a while, it will usually go just a tiny bit to the right, breaking in, and then will STAY right there.

That's good. I guess another way of saying what I said above is that the picture by itself doesn't really answer the relevant questions. :thumbup:
