Sebenza lock failure?

[skyhorse]

That was painfull to watch, he should really have got some knowledge behind him before even started to talk.... and talk, and talk.

The Sebenza is on my gonna get before I die bucket list of knives I have yet to score.Watching that kid do every possible thing he could too destroy one was enough TO GAG A MAGGOT!!!

I've watched his videos and he makes sense to me... but i admit to not know that much... i would love to get the facts...

for example, he says the non carbonized lock face develops lock rock over time... the angle of wear on the lock face "slips"... this makes sense and esp with chris not liking flicking because it creates excess wear...

I discussed this with Chris decades ago. The wear that occurs with "flicking" is not on the face of the lock; it's on the stop and the pivot pin. The stop pin gets "hammered" due to the extra force of stopping the movement of the blade. The pivot pin takes part of this hammering.
The lock engages a bit faster than when the blade is opened normally but there's no extra wear on it. In fact, since the system engages with more force, it moves deeper into the locking mechanism, engaging more of the blade than when it's opened normally, making it even more secure. Chris, and many other makers don't like the flicking because it hammers critical parts of the system and will undoubtedly cause premature wear on them, but the lock isn't a part that receives extra wear due to flicking.

the point of contact on the blade tang isn't the whole face of the lock... its merely a corner of it... if the corner keeps rubbing, then his statement sounds correct....

As it wears (and as the rest of the system wears as well, the blade, the pivot and the stop) the lock engages deeper and deeper into the base of blade making the lockup more and more secure.

Steve Rice needs to make a sticky concerning the entire topic of frame lock operation including some points about basic metallurgy regarding the properties of titanium i.e. galling whereby titanium tends to stick to whatever it comes into contact with like a tang for instance. I'm literally still mad that this individual has any type of knife business whatsoever when he is obviously so ignorant about so many knife specific subjects.

Who knows what this guys motives are. All i know is he's a salesman and his word
should be taken with a grain of salt.

A friend referred me to his youtube videos & website, so I took a look. Maybe I'm missing something, but some things he says are confusing to me. For example, he really likes Strider's designs & their frame-lock. I've heard/read before of the "crap vent" & having only a small part of the lock-bar in contact with the blade tang. He apparently accepts to almost inevitable blade-play that develops with a Strider. That's fine, however, I recall him commenting & writing that he doesn't understand why Chris Reeve did the ceramic ball as the contact point for the lock-bar face & the blade tang. I believe he said something about it being a small area. Well, isn't that what he likes about Striders, a small area?

Understandably, he likes Spyderco's compression lock & Cold Steel's Triad lock. Concerning the compression lock, he seems to favor blade-play &/or excessive wear over the "small" possibility that the lock will fail (& from his videos, the failure is from doing some questionable things to the folder). I had a waved Yojimbo for a couple yrs & recall how the compression lock wore fairly quickly due to the wave feature (Much quicker than a thumb-hole opening Yojimbo or Paramilitary, for example). The Triad lock is a very strong lock, doesn't seem to wear prematurely, & doesn't appear to develop blade-play. However, I believe he doesn't recommend it if one wants/needs quick deployment.

Nothing is perfect & there are advantages/disadvantages to everything. However, I "think" he's taking the lock issue to an extreme. Maybe someone else knows, but has he replicated his "lock failures" with another knife that's the same model?

So her prefers Striders, ok well i prefer CRK Knives but you dont see me bashing strider and thier character just because he spine wacked his small sebenza and it failed, then Mr. Reeve turned around and repaired his blade and he continues show no respect and abuses the small sebbie, come on the small sebbie is not made for that.
what a MORON!!!!

 

[DCDesigns]

The guy is clearly trying to prove something. When he couldnt cause the unum to fail, he spine wacked the bitch out of it, im sorry, that proves nothing other than he doesnt know how to treat his knives. The sebenza isnt a survival knife, it was NEVER intended to be. When i need an knife capable of taking a beating, I use a $50 (or less) fixed blade, not a god damn $500+ (in my case) Folder!!!! come on, that shit just doesnt make sense.

 

[Steel130]

The scary thing is on his website he has survival training videos .

:barf: survival training videos. he needs a CT scan!!

I hope for the sake of mankind that he doesn't reproduce....his stupidity needs to stop with him.

I think he got all butt hurt when he called Mr. Reeve about his 'defective' sebenza and Chris didn't kiss his butt and
apologize etc. He even goes as far as to say Chris sent back the knife with a late lockup so it wouldn't fail any more...

...The sebenza isnt a survival knife, it was NEVER intended to be. When i need an knife capable of taking a beating, I use a $50 (or less) fixed blade, not a god damn $500+ (in my case) Folder!!!! come on, that shit just doesnt make sense.

No specific disrespect to the quoted posters above as I just grabbed the last 2 that stuck in my head with points relevant to my own... But the fanboi level of this thread is off the charts.

Obviously a Small Sabenza isn't a "survival knife". But until he SENT BACK A BRAND NEW "god damn $500+ folder" to modify the " 'defective' " lockup, he was able to override the lock with hand pressure. I realize the guy contradicts himself in a few places and comes off in an aggressive manner against a product that you all really really like. But a thread that could have been a valuable discussion on locks and titanium, is six pages of name calling and butt-hurt. Also railing against the idea of applying pressure to the spine. Fine... Then why have a lock at all?

*What do you use your Small Sabenzas' for that they even need locks?
*Why does it even have a lock if you aren't supposed to put pressure on the spine?

I've read "seat-belt" arguments for locks, but what's the point if the seatbelt only works at speeds below 5 MPH. Apparently the lock has to wear down to be effective. Does it stop wearing once reaching that magic point? It seems to leave you with a small window of time that the lock is actually effective, but before blade play starts to develop and it needs to go back to the manufacturer. Also flicking them damages the lockup. So even the one hand opening loses and speed advantage and is merely a feature to save me the considerable effort of having to reach my other hand over to open my pocket knife.

There is no way the Sebenza would be more popular as a "slippy", the lock is most definitely a feature of the knife. Aside from a weak lock being pointless, is it not more dangerous than no lock at all? I carry a 4" fixed blade and small slipjoint for EDC, but have been looking at the Sebenza for days i can't carry a fixed blade. I don't expect a folder to be a fixed blade, but what I saw in this video was not what I expect from a "locking" folder. I should have picked up that Rukus off the exchange...

You got it all wrong, but go ahead and be naive.It seems your throwing your scattered thoughts in the thread, Ive owned an Umnumzaan for about a year, and the blade has not failed me once, and I've put it thru her paces, and she still going good with great lock up. Did you even view the videos? go ahead and pick up the Rukus it is a hell of a blade, but still not a CRK Knife!

 

[snowreaper1]

If your basing your opinion and experience on a sebenza from this guys video rather then real world use then you could come to a conclusion that sebenzas are weak and unsafe. That couldn't be farther from the truth. In the past year I've had over 15 sebenzas in my hand. Not one had a defective lock let alone blade play. They have served me well in every task ive thrown its way.
Now ill admit I dont stab things with my knives. He says his spine wack tests simulate stabbing motions. So he's testing a sebenza for tactical purposes. What's the point in that. Is that good scientific method to test for what it is clearly never meant to be. And by reading the comments on his videos I've seen multiple people say they now wont try a sebenza because they now think there not safe.

Then consider my previous post a request to be educated, but I don't recall asking for anecdotal observations about your Umnum? I'm glad "she" ( ) is "going good", but that doesn't really address any of the questions I posed. I guess I'm not the only one with "scattered thoughts"...

Thank you for your response Snowreaper1. It is a shame that people on YT took this guys video and opinion as representative of all Chris Reeves knives. I'd also like to say that my thoughts presented in my previous post were not formed entirely upon seeing his video. This thread had more impact on me than that vid. My thoughts after watching the vid were that the manufacturer recognized it as an issue and addressed it. Which is great, but expected for a knife even 1/4 of the cost. This thread is what lead to my post.

Almost everybody in this thread seemed to write off early lockup as common and a non-issue. I propose that it is an issue. Either a locking knife locks up or it doesn't. You're better off with a slip joint than a locking knife that doesn't really lock. I don't expect them to put it in a vise and hang hundreds of pounds of free weights on it, but damn. Closed it by hand? If you're saying it's an error, but a fluke, I can accept that. A bit weird they didn't check that considering the $$$ they charge, but I get that it happens with production knives.

 

[frontline29]

This is purely speculation on my part.

But judging from his negative attitude towards Chris Reeve, he probably asked if he could become an authorized CRK dealer and they turned him down after watching a few of his video's.

IMO he's not going to get very far as a dealer by bashing one of the most respected knife makers in history.

Nah, I wouldn't chalk it up to early lock up. I'd say it's far more likely that this guy either bent his lock bar off camera, or he damaged it previously by performing his all important spine whack tests.

If you want a folding knife that you can spine whack to your heart's content, go for one of those tri-ad locks that everyone is swearing by nowadays. Personally, I'd prefer knives that I can blow clean with just a strong puff. I've had two lock backs fail on me due to excess detritus in the lock mechanism, and although they were fine after I cleaned them out, those experiences have scared me a bit.

Thanks for posting "pure speculation". That was awesome, thought provoking, and was in no way a completely biased fanboi post.
