Axis lock failed?

the compression lock seems to be as reliable as anything out there, and there's no lock buttons to worry about.

Joe,
Aside from the fact that a compression lock is harder to unlock by accident, what makes it more reliable than say a liner lock?
 
Isstaipei, Yes, there is a big difference. I would say that the "new" 520 has an axis bar that rides up more on the blade tang than my old one. I also have a 5000 that has an axis bar setting very nicely on its tang also. I did not have a first production run 520 (at least not that I know of). I just hope this problem has been resolved on this knife. The only axis locks that I have are the 520 and the 5000. The new Auto-Resistor will soon be on its way. :)

I discovered very early after the axis lock introduction that it is very easy to experience a lock failure.

My comfort position to hold a working knife is with thumb on one side slab and forefinger on opposite side slab.

Interesting. Does anyone else here hold a knife like this? I can't imagine holding my knife like this, it feels like I could easily lose control of it.

They way I grip my knives, as I feel is the way most people do, my fingers are no where near the Axis lock button.

I've been carring my 710 almost every day for 3 years and I have never had the lock fail and I have never accidentally disengaged it.

Johnny,

Well, being more difficult to unlock by accident (I assume you mean by accidental finger engagement) is a pretty big increase in reliability. The compression lock is also much more resistant to spine pressure and spine whacks, because those things cause the lock to get pinched and grip more tightly (i.e., the finger-like projection on the lock gets pinched between the stop pin and the step on the tang, which locks it in place).

AHA!

That´s it. Guess the good one has a way about 3 mm?
 
Today I was banging the spine of my recently acquired 520A pretty fuggin hard directly on the sharp edge on my desk in all different manners of angles and places. No failure.
