i have always love my emersons....they are always my fav in my whole collection...cqc8, commander, cqc7, mini 7...and i always loved the rough look to them. i never thought the fit n finish was an issue.

but recently i watched a vid on youtube and the guy was saying when he open his emersons to half open position and shake the knife, the stop pin would rattle. so i went ahead and tried it on all my emersons....guess wat? it rattles

i was guessing it might be due to the fact that the stop pin and liners are made of titanium..and the titanium deforms after hard use? (waving it and after many openings)

anyone else experiencing the same thing? i really wish emerson change the liners back to stainless steels....there are few downsides to titanium (wears fast, flexible)

what do you guys think?

Hmm "flaw" Really? I might point you to the account posted of a Marine who used his Emerson to free himself and his fellow Marines before sticking the knife in a very deserving enemy. He didnt mention the flaw you found but maybe he just got lucky............Emersons are what they are and even the supreme court wont make you buy one. Not bashing you just saying look at the tool for what it is and if it serves its purpose. ymmv
 
u are missing the point.
this "rattle" could lead to potential structural failure (up and down play, lock failing)
if it is a "harduse" knife, it shouldn't even have that problem in the first place.

ps: my commander and mini 7 are rarely used and they have rattling in them already....my cqc8 is my user and the rattle is more serious on it.

You are missing the point. It's a floating stop pin. It's supposed to rotate so that the blade isn't hitting it in the same spot over and over again. This info came right from Emerson........
 
oh if its not a flaw then thats a relief. its just been bugging me because i thought its a structural flaw. now i can move on with my day
 
It's designed that way and it's been discussed: This is from one of those discussions:


The cammed stop pin isn't a new idea by any means and you're pretty much right on with why they exist, except that they're supposed to be making up for wear and tear rather than poor fit from the factory. Just rotate, tighten, and viola! no more blade play and an earlier lockup on liner/frame lock designs. In the one knife I have with this feature, I put blue locktite on the fastener. slightly OT but while we're talking stop pins:

The standard EKI floating stop pin has the same goal, it rotates itself so that the hardened blade tang takes longer to wear/dent the softer stop pin (which I think are still hardened, but not as much), I'd guess that its a necessary feature given how hard wave openings are on the stop pin and frame.

No, it really, really won't.
It is not a flaw, it is a design feature. It is known as a "floating stop pin."
It is free to rotate so that you don't end up wearing a flat on the pin. This prevents the up-and-down play you are concerned with. It does not promote it.
If it bug you though, just put some wadded up paper on one side of the pin in the liner. This will stop the rattle, but then you will have to rotate the pin yourself to prevent wearing a flat.

Ah crap, someone else posted the same info while I was typing.:)
