Holy Crap! I also live by a river in SW Michigan and I don't understand what just happened here! You must speak "East side of the Grand River" language...
 
I was in a gun store looking at a .357 mag revolver. The sales guy, who wasn't even born when I bought my first revolver--a Ruger Security-Six--was standing behind the counter opening the cylinder and slamming it shut with a flick of his wrist. I was out of there and didn't come back.

It looks sooo stupid to those who know about guns and so cool to people who don't.
 
Wise move, Michael. The only person qualified to test the knife to your satisfaction is you.
 
The Al Mar S2K is known to develop vertical blade play, this is a known and normal condition for this knife; it can be repaired. In other words an S2K with said play is not an indication that the knife has been abused; used yes.

I certainly would spine whack it within reason and I also would say I had spine whacked it in said manner if I did sell it.

[imagine I am a potential seller] -- I was honest, I was reasonable, but that prevented the sale.....hmmmm, now if I was unreasonable [lots of real hard SW] and dishonest [by claiming light SW] I might have sold the knife. GO FIGURE.

Honesty about any abuse is still abuse in the end.

Moderate abuse is still abuse in the end.
 
No doubt. I guess the nexus of our point here is what defines abuse.

I define abuse as anything that is abusive ;).

I agree that a spine whack (if done light enough) can have no detrimental effect on a liner lock. Steel has a fatigue limit, and as long as you don't surpass the stress of the fatigue limit it will never fail even after an infinite amount of cycles. My fear is that many spine whacks not only surpass the fatigue limit, but also the yield strength and actually deforms the lock bar. Since the force of a spine whack is arbitrary, I call it abusive in my book. I can understand your side of the argument in saying that what most people consider a spine whack does not surpass the yield strength of the lock bar and therefore does not harm the knife.
 
I guess that I should redefine what testing I do then as EVERY locking folder I get has the lock tested. I extend my index finger on my left hand and do a "spine tap" I guess. I have had a surprising amount of failures this way, and I feel if I can tap it without causing me pain then it is as realistic as if something hit the back of the blade in real usage and I would like to avoid closure on my fingers.

Just wondering if the "anti-whackers" also feel 5-10# pressure on a soft unsupported surface (finger) is still abusive, as I feel it is a close approximation of real life experiences after using knives for the last 20 or so years?

I'm not an "anti-whacker" :D:D Anyway, that's really kind of mild after watching A. Demko do spine wacks and overstrikes on the Triad system. He puts some huge dents in thr wood surfaces, hangs 100's of #'s of weight off the handles and no failures. A real spine wacker, to be sure. :)
 
I usually open them, look at them, make sure they lock, then use them. I know it's not quite as good of a test as the spine whack or hanging dumbells off it, but I haven't had one fail on me yet. I'm fortunate to have enough fixed blade knives not to want to do fixed blade uses with my folders.

I would not buy it either. Why would anyone mention that in a sale ad anyway? Because they must have a good idea that it jacked up the knife is what I'd think.

CJ65, you're killing me - that was funny.
 
Oh no not another spine whack thread. I started one last year let's see how far this one goes! Spine whacking is abuse... Anything mechanical can be broken if abused...
 
About the same to me as the "Oil Drum Test". Just what I want to hear as a Buyer about a knife FS...
 
if by "spine whack" ya mean a lite tap against a carpeted floor/the palm of your hand/etc (which is imho more accurately called a "spine TAP", and all ya ever need to do to check lockup) that doesnt hurt anything at all.

now if ya go nutz and hit it on a metal table/anvil/etc, well yes thats not a good thing lol, and isnt neccesary anyway.
