Spine Whack Test

The three closest pizza joints around here are Halal, so no ham or bacon.:(
But they give you extra cheese, and it's reasonably priced.:thumbup:
Always a confusing choice.
 
To the OP - as you can see this issue has been - well lets say - "vigorously debated".

My opinion - I treat any knife that "folds" like a slipjoint - whether it has a lock or not. Therefore - I think the spine whack test reveals nothing for me.

If I need to go "grape ape" with a knife I defer to my fixed blades.

A folding knife is a mechanical device that can fail, period. Some are stronger than others - but at the end of the day they can all fail.

A knife can be replaced - the full use of my hand or fingers after they are severely cut cannot.

Do they offer Canada goose as a topping up there in Canuckistan? Because they should.
 
I know, I like 'em too. I like the snow geese better, though. They winter here. Mmm, good eats.:thumbup:

So do you guys think cutting a pizza with extra cheese would be a legitimate indicator of lock integrity? Or would that be considered abuse? And if it's not abuse and the knife fails the pizza cut test, would that be considered grounds for warranty return? :confused:

You need a Spyderco for cutting extra cheese; I remember some people repeatedly calling them "Cheese Cutting Knives."
So it shouldn't void the Spyderco warranty.:D
 
You flamers need to go elsewhere so I can get some legitimate input here. I will ask again: How about periodic testing of the lock with a LIGHT spine tap?

That one's been done to death as well, and it goes exactly like this:

Here's the proper results:
"Yes."
"No."
"Perhaps."
"Yes!"
"No!"
"Um, not sure."
"Yes!!"
"No!!"
"I don't do it."
"YES!!!
NO!!!

Repeat as desired.

Seriously.
That's all you're going to get, just with more words (occasionally).
 
No, I don't absolutely think the spine whack test is the be all end all. However, any decent lock should be able to take it.

And yes, I see popcorn, beer and pizza here but it's not my kind of party without Crown and Coke.

As far as raising the knife over your head and full-on slamming the spine onto a hard surface, I think anyone who does that shouldn't own anything sharper than a crayon. But I do occasionally tap the spine on my wooden or plastic table just to have an idea of how the lock would hold should I ever need to stab the knife into something.

I don't think any real-world situation would ever require that much force directed straight at the spine, but as I said, there might come a situation in which you need to really jam the knife into something, and that might cause exactly the type of shock that would dislodge some knives from the locked position.

Good info, bro. Much appreciated. :thumbup:
 
"Dirt in the lock, excessive banging on the spine, wear and age, are all reasons to be careful. I've seen quite a few knives that were "killed by spine wack" by ignorant owners that expect more than can be expected from a knife lock. (Locks are tiny bits of machined close tolerance metal, heat treated and carefully fitted together to keep a folding knife as safe as possible.

Keep you knives clean, periodic testing of the lock with a LIGHT spine tap or forced close (keep your fingers out of the line of the blade).

Do not trust any lock 100% regardless of manufacturer's claims. Most manufacturers do the best they can, but pobody's nerfect. A finger or two is a terrible thing to waste."

I guess, based on the above quote by Sal Glesser, it should be renamed the spine tap test.
