wave too much?

Just purchased two cqc knives...mini 7 and 7. The 7 has had 0 problems but the mini 7's liner lock was replaced by EKI just after two weeks of break-in use. The lock up moved to 90%.
I love waving the knives...a lot. I know, I got problems. Can excessive waving really degrade, wear, or damage the knife?
 
The knife is designed to be waved, but just by the design of the liner lock the large force created by the wave will make it wear faster than opening it with the thumb disk. This is not exclusive to Emersons, but is the same for any titanuim liner or frame lock opened with a large amount of force.

I lube my Emerson up real well, and broke it in watching TV. Opening, and Closing the full arch of the blade from FULLU CLOSED, to Fully Open about 350 times.

Wave the knife only when really necessary.

Also, if the pivot is sufficiently smooth and well adjusted, it should be possible to "gently wave", that is wave with the minimal amount of energy to achieve lockup. I have some that can be waved nearly silently.
 
Silent? I love the "CLACK" from a forceful and fast Wave out of pocket! But seriously, doing so with force does put more pressure and wear against all contacting points (pivot, stop pin and linerlock interface). You can also do the opposite of what OM suggest. Tighten the pivot down a touch more than one might prefer to slow down the action for those hard pulls.
 
Generally, does playing with the knife (opening and waving) wear the lock to the point of failure?
When my m-cqc7 liner went to 90% I emailed EKI. They told me it needed to be sent in for service even though I told them that the blade was rock solid.

Failure? Not sure, you might find out inadvertently though. All mechanical things wear out, that much is a given across the board. Titanium is softer than steel, and everytime you crank that knife out of your pocket you are adding some microscopic deformation to the liner, it does build up over time and your liner (where the stop pin goes) will be ovaled.
 
I have wore out a 7 to the point where it has 90% lock up with vertical play (the liner lock flexes). With my zt 0620cf, its so smooth that a very light wave will open it no problem. I can also wave it out as hard as I want and the lockup is still the same. I guess the steel lock bar insert really does make sense on a wave knife. I think if EKI heat treated the lock bar or carburized it the problem would be fixed for the most part.
 
I'm pretty certain that you can rotate the stop pin to change your lock up. Regardless, I don't wave my Emersons very often. Only do it when necessary.
 
I wave away. Emerson will fix it. I also hard kinetic opened my 8 to the point the hole around the stop pin ovaled and rotating it did not fix it.

They corrected that too. I no longer do that at all. It was before I knew better.

But I do wave mine. And if it clacks into place, cool! I just don't slam it open every time, but one has to do it hard enough to get the blade fully opened.
 
On the subject of stop pins, I found something interesting. When partially open, my 7, a 2013 model has a solid pin, no movement. My mini-7 is a 2014 model with a loose pin, side to side and rotational movement. I know it's the pins because I swapped them to see.
 
I'm not trying to be "tacticool." I'm not sure what that even means.

But there are many times throughout the week when I have to hold onto something and I need a knife immediately, like feeding the cows. And it sure is handy to be able to open my knife and not have to drop a bale in the other hand, or a 100 lb. bag of feed I just hauled up on a ledge to pour into a feed bin.

And I sure can't climb up there with an open knife in one hand and a feed or seed bag in the other hand. Sure would be easy to slip and land on my own knife and kill myself.

So different strokes for different folks.

Sorry that's not more sexy for you. Or "tacticool."
 
BTW I do have a nice ESEE 4 I tried to use but it just gets in the way too much when you gotta climb around things. I prefer an Emerson, stays out of the way in a pocket until you need it.

The ESEE sure is a nice skinner, though.
