Sebenza lock failure?

Not open for further replies.
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
spine wacks on purpose and he's avoiding giving him an explanation of why it failed. I can accept he has a negative opinion about the sebenza. That's fine. But he's now
taking shots at Mr. Reeve character.
 
Exactly Snowreaper, this dude is total B.S. he's over here talking good about strider, and i'm ok with that, but just because they show him alittle attention at the gathering he about creams his pants, Hey dude if you dont like Chris Reeve Knives, don't buy them and move on, more for me to purchase.
 
Anytime someone tells me that he's "an expert" (as this guy does) I tend to tune out anything that comes after that.

His logic and reasoning is so biased and full of holes. I own both an SNG and a Large Sebenza and I can definitly say the CRK is tougher, better constructed, more reliable, thicker titanium, has a smaller lockbar cutout, much superior tolerances, easier to maintain and take apart, smoother, more practical, better slicing/cutting performance, better pivot system, much more durable, and definitly has a more solid/safe lockup than the Strider. None of these arguments are really debatable either... Whatever, he's entitled to his misinformed opinion I guess.
 
This guy knows very little to nothing about titanium, lock bar faces, tang, tang angles, and even less about engineering and physics. He contradicts himself constantly as a result of complete ignorance regarding his subject matter. So much so I'm mad that this much misinformation and out right erroneous information out there with some poor fool buying it as gospel. What a tremendous disservice this misguided, misinformed and ignorant individual is responsible for, sad, just sad.
 
I could not make it through the whole video, he moved around the knives so much it was almost dizzying. I would would never take this guys word about locks, or CRK. I would never spine whack a Sebenza and then call it no good. I totally trust my CRK Sebenza, and Umnumzaan. I would never stop carrying them based on this guys test which I find ridiculous.

What I found hilarious was that he kept spine whacking the crap out of the Sebenza in the video, trying his best to get it to fail and it wouldnt fail. He then accused Mr. Reeve of intentionally messing with his Sebenza so that it wouldnt fail anymore.... lol I just dont get it.

Is that what he is saying? (Cant watch the video)
 
as someone relatively new, is there any way someone can make a rebuttal video or post the points he made and show a counter argument???

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... 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....

is there something else going on that i don't see??
 
That was painfull to watch, he should really have got some knowledge behind him before even started to talk.... and talk, and talk.
 
One thing I found amusing is that he complains that one thing he does not like is that you can't assemble the knife without a flat surface. Thing is, you can if you know how to properly assemble/disassemble the knife. He does not. According to Mr. Reeve, you remove the pivot pin and then slide the blade out before removing the other pins and separating the titanium handles. Assembly is the opposite. Put the handles together and tighten down the pins (important). Then slide the blade, bushing, and washers assembly into the assembled handle and install the pivot pin. This guy thinks he has an Umnumzaan apparently?
 
OK. I think I figured this guy out and here is the problem. When he was 'brand new' out of his mother's womb the nutty doctor decided to spine whack test him against the delivery table. The doctor has since spent the rest of his life blaming the mother for the results!
 
Seriously though I think it is clear that this guy simply has a vendetta out for Mr. Reeve and his knives. Nothing could be more clear. In addition, he does not understand economics at all. Nor does he understand proper scientific method. Notice how when he first spine whacks the Sebenza he fails to produce failure. So, he adds some water (claiming that it is just water and not oil) and tries again. This time the lock fails. If it did not would he THEN have tried some oil? If he thinks that water is not a lubricant then I guess he has never driven a car down a wet road. Then...he starts spine whacking a Sage 2. The lock holds but he then does not add water and repeat the test as he did with the Sebenza. Bad scientific method here. He later shows that there was damage to the Sebenza lock bar but none to the Sage. Well...that could be because he did not test the Sage in a similar manner (causing the lock to fail by adding water).

He also concludes that you are getting the same quality with the Sage 2 as with the Sebenza for half the price. No kidding. The Sage is made in Taiwan if I remember correctly. How can you compare a knife made in Taiwan to one made in the USA on price? Makes no sense. I do not own the Sage 2 but I am sure it is a great knife as are pretty much all Spydercos. I do own some and am very happy with them.

He also seems to think that 'fit and finish' refer to sand blasting of Titanium. I guess that pretty much says it all!

He then concludes that the Sebenza's lock bar will eventually wear to the point that it will contact the opposite side handle. But...I seam to remember that being a good thing in his opinion when considering other brands. A good thing in that, even though you may get some blade play, the lock itself will not fail.

Bottom line is that this is all quite foolish anyway. I have been using knives of all type for 40 years and have never had one fail. Then again, I have never had to drive nails with the spine of any knife nor have I been attacked by a refrigerator door! I wonder if there are any knives out there can can withstand the impact from a 30-06 rifle round and show little to now damage? If so, I think I will make a video concluding that all other knives are somehow defective and dangerous and to be avoided at all costs.

Here's a post I made in another thread:

The contact area of any lock can be peened or deformed by repeated impacts (abuse). The problem with longevity for framelocks/liner locks is that although some consideration is given to allow for self adjustment (by providing an arc or line across the back of the blade tang), the material used for the lock is often softer than the blade steel against which it interfaces. Thus, one can see the deformation that occurs when non-heat treated titanium lockbar "wears" in. Take a look at the end of your BM's lockbar. I'm fairly certain you will see that the titanium has an indentation.

Higher end titanium knives often (and in my opinion should) take into consideration this type of deformation: for, when wear of this type occurs, the only solution is to replace the stop pin with another pin of a larger diameter, or to replace an entire slab of titanium. Chris Reeve, the originator of the framelock, appears to have recognized this problem and he has the Sebenza's lockbar face heat-treated, and on the Umnumzaan he put a ceramic ball which has a higher hardness than the blade. Lionsteel and Spyderco (on the latest iterations of the titanium Military) address this problem by utilizing a replaceable steel insert.

The whole thing with Chris Reeve saying you shouldn't flick a Sebenza is a big myth--usually used by people either misinformed and ignorant of the topic, or by people who, for whatever reason, seem to have a vendetta against the knife. Mr. Reeve in fact encourages a couple of wrist flicks after re-assembly of the knife to seat the lock properly--what he doesn't encourage is the continual and hard flicking of the knife for hours at a time. I believe he made some kind of analogy to buying a Porsche: it is a well made car, but for some reason you really enjoy the sound the door makes when it slams shut, so you open and slam it shut many thousands of times--even a car made like a Porsche isn't designed for the end user to continually open/close the door obsessively.

STR has made several great threads on frame lock design, especially with respect to how the lock bar face interfaces with the blade tang. Do a search of STR's posts and threads on frame locks.
 
Excellent.. Thx for pointing me in the right direction

:thumbup: i really want to keep this thread alive, just so people know the facts and not B.S. or some kind of vendetta this guyz has against Chris Reeve and his knives.
 
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.
