How do knife manufactures test knife locks for strength?



and



Has anyone ever broke or has the lock ever failed on any of your better quality knifes? If so what were you doing with it??



Thanks

Spyderco fixes the handle in a vise and puts pressure on the blade, if I remember correctly. <img src="spyder.gif" width=15 height=15 align=middle border=0>, along with Cold Steel, are the only companies willing to put lock strength data out for public consumption, while most simply claim to have the "strongest lock anywhere" but give no proof.

See the other Lock Strength query for more.

I've never broken a good knife, though I have intentionally broken some cheap knives, just to see how far they will go.


Never underestimate the impossible.

I had a Gerber International AR 3.00 linerlock that would fail with a sharp whack to the spine of the blade. I have tested another AR 3.0 and that particular knife passed the spine whack test fine. Guess I just got a bad one. My other knives of differing brands and of course, my Spydies have never let me down. I no longer own a Gerber AR 3.0. More interestingly, my Dad has a Gerber EZ-Out Jr. which will crumble with slight pressure on the spine of the blade...scary.

I've only had 1 knife go on me so far, and during use. I had a Gerber Gator and was whitling with it on a survival exersize with cadets. The pivot gave out on the 4th day of owning one. I only had it for about 30sec after it gave. Retry close/open, and then chucked into the wood. The officer's son had a Gator this last spring, 2yrs after I hucked mine, so it could be the same knife. I just didn't feel it was worth hauling back to my bag.

As far as I can remember from my dealer video(haven't watched in about 2 months), spyderco puts the blade in a vice just past the pivot, and puts force in the closing direction on the lock. The delica/endura in the vid just snaps a bit.

<img src="spyder.gif" width=15 height=15 align=middle border=0> also offers a breaking service. If you desire, they will break your lock for a fee and give you the results.

It helps new makers or makers trying a new lock. The info is only for your personal consumtion, not to be used for public, but its there.

Sal posted this service over in the Bladesmith's section of BFC... and a price I beleive.

Let's face it guys, ANYTHING is as

"imperfect" as those who(m) made it.

Look at the multi-million dollar

Space Shuttle "Challenger"<img src="sad.gif" width=15 height=15 align=middle border=0> ****,

look at the "Hindenburg". THERE WILL

BE NO PERFECTION AS MAN IS IMPERFECT!

Sh*t, look even at the early M-16, then

the "A1" that followed, now 40

(count'em!) years later the M-16A3!<img src="sad.gif" width=15 height=15 align=middle border=0>

which, I understand, STILL has

PROBLEMS! We can sit here at Our "idiot

boxes of the 21st Century" and debate,

compare apples & oranges. So what!?!

Have there been no post(s) here with

forumite(s) complaining of something

of one way, manner, shape or form WRONG

with their precious Spydies?

IMB it's ALL the same sh*t to me!

Allen,

I'll take a good old M-14 (308) over an M-16 (223) ANY day of the week (including Sunday).

Quite interesting! Risking to slide off the topic, I'd pick an Ak-47 over any M-16 (no offense my American friends).
Yet I heard that the Galil (made in Israel) is by far the best among machine guns.

The SAS prefers to use the M16A3 than the SA80 disgrace that the British Government gives to our Squaddies to use.

DiALEX -

AK? ANYDAY!!!!!!<img src="wink.gif" width=15 height=15 align=middle border=0>

M16? M14? Boys, take an Ak of "hundred series". ABSOLUTELY RELIABLE MACHINE. No offence to anyone around.

Wow! A brand new year and we’re already this far off topic! C<img src="spyder.gif" width=15 height=15 align=middle border=0><img src="spyder.gif" width=15 height=15 align=middle border=0>L! Let’s try and keep it to Assault Weapons and Light MGs though or else someone will call for low yield tactical nuclear weapons and there goes the neighborhood, the borough, the district, the city, and maybe even a small state!<img src="wink.gif" width=15 height=15 align=middle border=0>

I prefer the M242 Squad Automatic Weapon Still uses the light NATO 5.56 round but 750 of em per minute effectively applied at 800 meters – gives you a whole lot of Hello when you want to reach out and touch someone. Nothing better for targeting OPFOR automatic weapons, key weapons, and command and control elements. Once those are gone, you’re free to engage whatever’s left with enfilading fires across the platoon front.

Geez!!!!

OK, java, I'll up yer SAW with a MK-19 Auto Grenade laucher. <img src="spyder.gif" width=15 height=15 align=middle border=0><img src="tongue.gif" width=15 height=15 align=middle border=0><img src="spyder.gif" width=15 height=15 align=middle border=0>

Now, fer an average man carried bullet launcher, I'll have to give the AK the nod fer plain A%@ reliability and fuctionality.

Though having fired both the AK and the verable M-16 (thru the A2 versiion) I have to say that it is a very awesome weapon in its own right - particularly for the squad infantry man

There is no right way to do a wrong thing

armalite AR-50. yes, i know it's not an auto... but, it's just so **** huge. anyway, yeah, take care
hey java, liked the sig on that one.

sven

steel is unforgiving... sharp steel even more so

Chuck,

You'll definitely get my attention with that puppy, but you better be able to run the 400 meters in practically nothing once you've launched. The SAW is most effective at 800 meters on in. Max range on the launcher is 400 meters. But I think we're both a little hard pressed from Sniper-Sven with his Armalite AR-50. Them BIG rounds will make your day in a heartbeat as they (hopefully) zing by. I prefer the lighter Barrett Firearms M82-1A1 for my long distance calls though. Nice choices both, guys!!

Wonder why no-one's picked one of these for their team yet???<img src="http://www.engr.uconn.edu/~mmartins/smi ... hrower.gif">

<b>Happiness is a belt-fed weapon!</b>

I agree with JAVA. The M249 SAW is about the most perfectly designed weapon I've ever handled. This includes easy cleaning and functional reliability. As far as blades go, I enjoy my Delica PE.

Give me a classic 303 or 30.08 and I'm happy...

not the fastest or most powerful... but deadly accurate for a good ways. Especially with my 40x scope on the 303... little overkill for target shooting, but it's FUN.

My Word, My Honour, is my Life.

It's interesting to note that the reason that the Automatika Kalashnikov (AK) variants are the most reliable, popular battle rifle in the world is that because of their loose manufacturing tolerances, they're very resistant to jamming, even when full of mud.

And Allen, things haver changed quite a bit with the M16 since the first A1 version... the A2s and A3s are different beasts entirely!

Personally I'm a fan of the various Samozaryadnyi Karabin Sisyemi Simonova (SKS) variants... a highly underrated rifle in many cases.

Also, I'm anxious to try one of the Spanish Cetme rifles in 7.62 NATO. If only I could stop buying Spydercos long enough to pay for one... lol...
