Spine whacking? WHY????

[bodog]

Its a test that does not truly prove anything. But people fetishize "hard use" folders and makers happily oblige with ,25" thick prybars so people with too much spare money can feel cool claiming they batoned with a folder.
The closest thing I get to a spine wack is putting a lot of thumb pressure on the blade to see if the lock will fail to date, a CRKT and the DPX HEST are the only to fail that test.

I wouldn't say a spyderco military is a fetishized "hard use" pry bar, but I still want it to have a reliable lock. I have a spyderco mantra on the way. That's an upgraded delica for all intents and purposes. Guess what? I still want it to have a reliable lock. Don't know why that's so hard to understand. Reliability means things have been tested. Testing is meant to be demanding. Demanding testing means overkill to make sure what's supposed to be actually is. In the mechanical world most things are tested to failure so that it's a known and quantifiable failure that can be accounted for. I really don't know why people think so differently about a mechanical tool like a knife. You think most every part of an airplane isn't tested to failure? You think most car parts aren't tested to failure? You think most power tools aren't tested to failure? Yeah, they are, because companies get sued when they put crap parts on things people rely on and subsequently get hurt by due to manufacturer negligence.

I'm sure it is just getting each other's goat at this point in this thread haha....

Well, let me pose this . . .

What if you take your latest purchase (w/ a lock, of course), and just give it a MILD spine-whack (like just on your knee -- not very hard at all) . . . and it fails?

Then you're out of luck or doesn't matter, depending on whom you ask.

Buy a knife with a well engineered lock and light spine whacking isn't necessary. A well made lock should be strong enough that any info gained will be from destructive testing.

This isn't going to make me very popular, but don't buy a frame, liner, or back lock and you won't need to test for hard use. They just aren't a well engineered lock and some examples work just fine but others, even of the same model, just don't hold up and the lock will slip and fail with light to moderate forces.

If I want a heavy duty folder that I can be confident in should I somehow need it in a crazy, extreme situation, the 3 above locks will not be on my knife regardless the maker or how beefy it is. Those locks just aren't designed to put forces on parts that can handle high forces and that can't potentially slip.

I'm very curious as to exactly what type of locks and specific brand name knifes that you DO recommend for " a crazy , extreme situation " and why ? All you've stated are negatives . So what are your positives and your proofs ?

You've proven you can count to 10 and find it necessary to comment in a thread you apparently despise ? Why bother yourself ?

Hi there. Honestly didn’t read through the tons of pages on the net about this subject ‘cause it’s not something I am very interested about . But I’ve read through the thread here and, as knives hobbyist I am now a bit confused. The “spine whacking” thing, in my neck of the woods it’s known as table test. Basically, in this very scientific test , the spine of the blade is hammered on a table top corner (or something of the kind) to see if the lock disengages or not. To me, for my type of use, this test means from very little to nothing, I don’t use spines of the blades to hammer stuff around. But this is completely different from a stabbing test. I do stab things with my knives (not that often but it ‘s rather common: cans, HDPE containers, etc.) and I test the stabbing capability. For me a locking folder need to pass this test, I buy locking folders exactly to have a blade which stays locked during cutting operations. Stabbing is part of the cutting operations. So I am confused.

It looks to me this operation:

has nothing to with this one:

Can some expert help me out to understand better? The forces involved looks to me really different and the two things seems to have very little in common. Thanks!

Mr. Herlock, apologies, but may I offer my sincere recommendation for you to see a professional manicurist about those cuticles.

Bwahaha!

Absolutely no need to apologize Madam! Thanks for your honest feedback. On the contrary, I am the one owning Ladies and Gentlemen here some apologies for showing my such uncared hands publicly. An almost i-n-d-e-c-e-n-t show! Actually my wife often tells me the same, I see she has a point now. I know ‘ll be daring now, knowing you so little, but, I am recently torn about what to do with the hairs on my chest. What would be your precious suggestion about: shall I get rid of those completely, leave them "wild" as they are or proceed with a “moderate” grooming? Really looking forward to entertain an educated and civilized discussion on the topic, maybe in the suitable place it would belong: Razors, Scissors & Personal Grooming.

Thanks Mr. Mecha, I had a good laugh! You make some nice swords as well! But now I’m dangerously OT. Out from here! Fast! Have a good one!

Id send it back for repair.

Well, as a new member, I guess that's my nice welcome to the forum message!
In any event, I think spine whacking is for those who tend to seek perfect fixed blade performance in a folder. And the harder it can be spine whacked, the "better" the folder is. I don't necessarily agree but that's my perception of those who place weight on that performance test.

emf, you will get all your folders out, even those you have been happy with for years, and give them a whack test. Because you haven't thought too much about how to do it you might just ding your perfectly nice work table before realising something less important should have been used. Then you test all your folders and non fail your test, or just one does. It murphy's law that its the blade you have been happily using for yonks. Now you might lose trust in it! Or realise its filthy and needs a clean. Finding a knife that fails the test can be difficult, and when you do repeating the fail often just doesn't happen. Do the test again a month later and get a different result and thats not repeatable either. A well constructed folder with a good lock will do whats require and its pretty obvious if its not doing it.

Most folders have a more than adequate lock for the strength of the knife; best if they are kept clean.
Some cheapo folder might just be rubbish and obviously so.
Any mechanical lock can go wrong, just don't absolutely trust them and try not to load them with huge forces. Cutting stuff doesn't need much force if the edge is sharp.

So at the end of the day its not very important. Do the test if you want even if its just to see that the lock can; the vast majority do anyway with moderate force.

As said the topic has been done to death and some think its a worthy test and others not so much. All the rest of the banter is for banter's sake.

Have you gotten your answer
If not we can go on

Oh I was just joking around, Herlock.

But since you asked, I recommend strips of Gorilla tape for the removal of unwanted hair.
