Spine whacking? WHY????

[bodog]

Bodog, it's all about the knives. It's like motorcycles, I'm happy people are ridin' I'm not gonna get hung up on the type or make of bike you ride, hell it gives us somethin' to talk about it's just that you can only talk about which headlight cover is best for off road when the farthest off road most people get is their driveway in the snow. This is one of those subjects that with a quick Google search turns up tons of reading material and in 20 years of talkin' to a lot of the members here about the same topic we've never gotten anywhere with it. Kinda like the old "Is a Sebenza(or insert any midtech knife company here) really worth the money?"

Haha. I think vance and Hines pipes are overpriced.

Somewhere along the line we convinced ourselves we need locks that will support a Buick in case we ever find ourselves surrounded by ninjas in a jungle.

This!!!

Since the tactical craze starting in the 1980's and the Buck 110 in the 1960's before that, we have at least two or three generations now that have never carried or handled a knife with no lock. They can't comprehend not having a lock on a knife, yet many generations of people got by fen with plain old friction folders or slip joints. I remember growing up with just slip joints, and nobody got any fingers cut off. To this day I carry a slip joint, and the whole obsession about lock strength has always puzzled me. Spine sacks? Never heard of that until a few years ago.

This slip joint has had 70 years of service, and never let the owner down. It's done everything from opening mail and gutting trout, to field dressing deer. About 1/3 of the blade has been sharpened away, but it's still ready to go. It would fail a spine whack. though.

Well, a fat woman who doesn't ask for much and is absolutely reliable and loyal is better than a hot woman good at nothing.

I'd rather jerk off thinking about the hot woman... which I do

I only spine wack my kitchen knives when I need to pulverize without pulling out a blender.
Never with my pocket knives.

I do have to admit one time when I wish I woulda had a good lockblade over a slipjoint. I was 15, my Old Man had just died and I was actin' out like a 15 year old kid would and in a fit of teenage angst I took out an SAK and with all the might a teenager could muster I stabbed a telephone pole . Yes the knife closed like store in a state with blue laws on Sunday and I nearly cut my finger off, the only thing that stopped it was the bone in my finger. In all honesty it wasn't the fault of the knife, it was the stupidity of the operator that nearly cost me my finger.

What can I say, hey I even sharpened knives on cinder blocks when I was younger but with age hopefully comes experience and as the tool changes you learn to use the tool and use it correctly. I don't ever recall in 40+ years of carrying a knife that I've ever used the back of the blade to cut with.

You know what the other part of this is? Being a mechanic/machinist/tradesman I've always held a high degree of respect for tools, if you use something as simple as a micrometer and use it to tap finishing nails into a wall it'll do it but I wouldn't trust it's accuracy micrometer anymore and it didn't even make a good hammer. I get improvising when necessary hell as a fabricator you improvise all the time but never to the extent of ruining my tool. I don't recall the details of your original story about the bike chain and knife but unless it was a matter of life and death or a $5 knife I didn't mind ruining I woulda found a better way. You'd be amazed at the stuff you find if you're always lookin' around at the ground.

I guess there is always be people who spine-whack and baton knives till they make the backs of the blades out of Mercury Fulminate.

Good Lord, I could film an action movie based on some of these spine whacking "scenarios"

And it could win an Oscar

Screw spine whack test. Do it with Sebenza*:

Knives for SD is ridiculous in itself.

It's only advantage over running away would be in a sneaky offensive type situation....
Better off with some pepper spray and a good pair of running shoes.

It really doesn't matter what you think about knives for SD. It's the people who do carry folders for SD who want to have reliable locks.

BTW, that's also called the strawman argument.

Exactly. Different people have different abilities (or lack of). Fixed blades are best, but depending on your location and laws, you may have to rely on a folder.

It might suck, but that's when you need a lock that won't give when you are in a nasty situation.

 

[Peter Hartwig]

It failed because its only ti lock against 60 hrc S35VN. Titanium is strong considering it's weight but isn't that good at shock resist.

.

I think this gets to the point of the problem. Ti flexes. If you think someone or something is going to be whacking on the spine of your knife, the ti framelock may not be for you. Under normal use & conditions I see no reason for it to fail. Like many things in life there are trade offs.
What you do with a knife and how you use it should be taken in to consideration on what you buy. There is a knife out there for everyone, but not one knife for everyone.
Makers design for what they have in mind and that may not cover everything you can come up with to make a knife fail, be it spine whacks or battoning through redwoods.

Excellent point. Nailed it.

Slipjoint even if doesn't have lock, works different than failed framelock.

That weight is around 2 kg.

 

[ourgon]

And those two are together a little bit heavier than 2kg.

 

[bt93]

Slipjoint even if doesn't have lock, works different than failed framelock.

Alrighty now. Anyone who has concerns about a lock failing on your folder, stop what your doing. Go out and buy a slipjoint and live with it for a solid 6 months. Once you get used to using a slip joint knowing that if you don't use it right you'll lose your fingers, then you will never worry about a lock failing on your knife ever again.

That would be better.

I test all my locking knives to make sure the lock works. I first try to close them with my hand and then with a light wack on the edge of a table.

I have had Spyderco, Buck, Cold Steel and Terzuola custom ACTF fail this test. I sent back the Spyderco to be fixed and fixed the Buck and Terzuola myself.

I do this test because I had a knife close on my hand while using it to cut weeds next to a fence in my yard. The spine hit the fence with a moderate amount of force and the blade closed, luckily there were some thick weeds to keep my fingers safe. This is proof the spine whack test has a legitimate place in knife testing.

I have asked manufacturer reps and custom knife makers if their knives would fail a moderate tap on the spine. They all say their knives should pass and that the whack test is legitimate.

My sebenza just passed my spine whack test...again.
