Sebenza flicking

[The Aflac Duck]

What is the difference between a flick, and the flip of a flipper? Or a spydy drop? Idk, seems rather odd that a normal use knife couldn't handle those forces.

This is like being scared of a gun failing because the bullet firing puts too much stress on the frame. Unless the knife is a dainty piece of jewelry (aka safe queen), I wouldn't worry about it. The components are made of titanium, and hardened steel. I would be surprised if they failed from a human flicking it repeatedly, even after years. If the Sebenza has the build quality it claims, there should be no problems.

There are no "claims" or "couldn't handle" about said knife.

Mr. Reeve is well aware of the people that will sit there and watch a movie while wrist-flicking their Sebenza full-force for 2+ hours repeatedly. People like that deserve to have their warranty voided...

It's no different than a "Disassembly will void warranty" note. It's there for those that will abuse such a privilege.

I don't know how acurate the analogy is.....a gun is DESIGNED to fire. Whereas CRK specifically states it was NOT designed to be flicked.

I also don't think it has anything to do with "build quality." The materials used are nothing but premium. I believe it is when you take the different hardness of each material and then put them in contact with each other that unnecessary wear will take place.

It's how diamonds cut concrete. Both incredibly hard materials separate from each other, but if you rub a diamond hard enough repeatedly on concrete....IIIIIT WEEEELL CUT

I was under the impression that the Sebenza is popular due to its excellent craftsmanship (that would be the seling point, and people claim its the best knife ever, all that). I must say though, I really don't know if full force flicking a Sebenza for even 2 hours would cause any sort of performance impairment. I have a hard time believeing that hardened steel and titanium could fail just like that, but my lack of experience is evident. Everything has a lifespan, but the effect of flicking a knife feels like it wouldn't affect it significantly.

I never said that 2+ hours of flicking a Sebenza would cause issues...maybe I wrote that wrong, or maybe you read into it too much. My example was describing people that do this repeatedly.

I've seen people ("collectors") wrist-flick their $1,000+ knives (damn hard!). Personally, it makes me cringe.

The Sebenza can handle it, trust me. But that note about "don't wrist flick your knives" is more about CYA than anything else. Refer back to my sentiment about disassembly if you're confused.

Very very true, your comparison to concrete makes is applicable (to the frame lock too). Perhaps I should have asked, are the stop pins on the sebenza steel or titanium? If titanium, then I can see how flicking would ruin that (45 hrc vs 60 hrc in a general sense...ouch). But if it is steel on steel, I think it would be fine.

By build quality, I meant both f&f and materials, both of which factor into the lifespan of the knife. If someone comes here and says that the stop pins are titanium, I will be legitamtely surprised. I also wasn't aware that the sebenza specifically states it should not be flicked, guess that nullifies the gun analogy. Has anyone experienced blade play, poor centering, or other issues with a sebenza? I handled one, and it seems solid, but the warranty is very picky, which I find strange for a knife. I guess Reeve is protecting his business from people who don't know how to handle knives, which is smart.

Perhaps I misunderstood your last post, yes, it does make sense. I guess Reeve is protecting the business against people who don't know any better, which is quite smart on his end. And if I saw someone Batman-flicking a Rockstead, or using one as a prybar or something like that, I would probably die a little more inside

 

[Sosa]

So when buying a used sebenza online is it out of line to ask the seller if he or a previous owner wrist flicked the knife reapeatedly? How do you check for this type of missuse? Has anyone actually been declined by reeve for warranty service? I gots to know.

Stop pins are steel, I can't speak for certain to the hardness. Just my own assumption, but I would imagine they are less hard than the blade. I know you can shatter two hammers when you smack them together if they are around the same hardness. Which is why nail pullers are typically of a softer metal and a well used nail puller is usually "mushroomed" at the point of repeated impacts. Otherwise they would do the same when you hit them with a hammer.

I would imagine this would be the case when two steel objects impact. This would lead me to believe the stop pins would have to be softer than the blade. Maybe Repeated hard slams of the blade could dent the stop pins thus causing blade play???

 

[cricketdave]

There was a huge thread in the Reeve forum a year or two ago about this, as I recall the lock bar face was the point of damage. Not the stop pins, it was the face of the bar where it contacts the blade that was beat like a rented mule. To the point of deformation.

 

[Brusiedmeat]

I cannot flick my 25 even if I wanted to.. The detent is too stong and not made to be flicked..

I've seen it...I won't name names though. If you're reading this, you know who you are

I've heard that CRK knows when a knife has been "flicked beyond warranty". I'm not saying this is fact though, I truly don't know.

Slightly off topic: I had an Estwing rock pick "explode" under use. I was picking away at some concrete and suddenly I felt a sharp pain in my left (non dominant) hand. I used my Sebenza (ironically) to pick out a large piece of steel from under my skin.

I concluded that the hammer had shattered and embedded a piece of steel in my hand. I was right, since the piece of steel fit perfectly into a broken part of my pick.

Take it for what it's worth:thumbup:

You're not going to ruin a Sebenza by forcefully wrist-flicking it over and over while watching a two hour movie. But it won't be the same knife it was when you started the movie.

Over time such violent opening will weaken, maybe slightly deform, some of the components. If you want a lifetime tight knife, and most of us who spend $500+ on knives do, don't do it.

Ever see those ultra slo-mo films of fighters being hit in the face or jaw? In real time it didn't look like much before the guy fell. But ultra-slow you see the moment of the shock wave traveling his jawline, his neck stretching like rubber in the instant it goes to twice its length, and his jaw twist up to his ear as sweat flies like a disco light.

I think you'd see similar stresses were someone to film a hard wrist flick on a liner or frame-lock folder....not only the shock and flexing of the stop pin as it is hit by the blade kick, but the dissemination of the shock through the pin and into the liner and scales at all points of contact and attachment. You might see the lock slap over farther than its usual travel as the blade is extended beyond anything it sees in a normal opening, then crashes back down on the lockface, and the resulting shock and deformation travelling back down the liner or frame. The stresses on the pivot internals from such actions wouldn't show as it's hidden.

It's what happens on a micro-level and in micro-time with each of those 50-g wrist openings that would worry me long term.

Hahaha! Best. Analogy. Ever. :thumbup: This post should be stickied somewhere just because of its sheer awesomeness.

I get the mechanics of the "problem" of flicking a $500 Sebenza.
I'm just trying to figure out how the mfgrs. of $30 spring-assisted knives get around the physics of this self-destructive behavior.

 

[cricketdave]

Steel lock frames not titanium, even more expensive versions like the zt knives have a steel insert now to prevent the titanium from excessive wear.

 

[Makael]

As expensive as they are. You should be able to flick the thing. I have one and flick it. I don't have any issues.

 

[stabman]

Thumb flicking is totally fine.

If you want to do full-arm "Thwacks!!!" like a human clay pigeon thrower, well, two things:
1) You look like an idiot.
2) Just man-up and buy a new knife if you screw it up while looking like an idiot.

 

[Sosa]

There's nothing wrong with a centrifugal whack every now and then as long as it's your knife and done for your own enjoyment away from prying eyes. And a quality folder should be able to take it.
