jdavis882 sebenza cutting test

[JNewell]

That's basically it...thanks.

If I understand him correctly, he is saying there could be many more of them with a poor HT. But since most people keep their CRKs in boxes and never use them, (unlike you) if there are defective ones, they are unlikely to surface.

He was meaning 42 degrees. The * symbol means degrees, if I remember correctly.

And it didn't come from the factory that way, I actually had to thin it out to get it to 42.

42 rockwell? Seriously?

Also, like many others that make such reviews, there are going to be detractors of information. Criticism on methodology. It's the nature of what you chose to make a video of. Good, bad or indifferent.
CTS- do not take this as a flame..I have no such intentions.
Problems are normally solved through the normal channels such as the manufacturer..But I can see a case being made when a review doesn't necessarily go as one might have liked. The review is just that..a report on the product..good, bad or indifferent.

I hope all this gets settled...being a CRK fan myself..It's very hard to see these kinds of results.
I will hold off on cutting my rope into a 1000 pieces (there goes the plans for this weekends festivities)

Ohhh...42°
Gotcha...the asterisk got me..makes more sense now. Thanks for the clarification to both

What * bevel do you guess it arrived with?

Sebenzas come at about 30 degrees, you didn't have to thin it out to get to 42 degrees. If you thinned it out, it would be less than the factory angle.

CrimsonTideShooter had a "not positive" run-in a few months ago with CRK...thus any negative test of a sebenza by him must be viewed with suspicion. He claims he specifically did not want to bring it up on this forum, but he is having great fun responding to this thread...troll? He was also specifically asked by CRK to bring his problems to them first, not to the public.

Personally, I like to treat people, the way I would like to be treated. If my customer has a problem, I'd like them to talk to me before going to trial by internet.

What I saw was a man using all his weight for many cuts done primarily with a 2cm section of blade. The edge bent. Not all that suprising. I've had edges bend in many ways on a varitey of knives. Higher rockwell ones break, that's why the old dudes like medium hard carbon steel.

Excellent answer! I've bent the edge on a one-piece Project I (my own fault by hacking away at wood and striking the wood slightly angled). I remember that I was pleased that it bent and didn't break. It seems to me we are living in times where everybody else gets blamed for our own slip-ups!

Except this was just rope.

 

[marthinus]

There is something wrong with that blade, be it heat treat or not.

The video could easily have stayed private between CRK and CST. One does have the option to change who can view videos on your youtube by adjusting the private policy option that is given for every video.

I also tested the edge on wood, a tire and cardboard box.

Fine it is S30V, but still, proper HT is required and S35V is an improvement on S30V in elements and it should perform at least to this level or else something is wrong.

CRK wanted to keep this private, why, well same reason why many other manufactures have also stated, give them chance to make it right before running to the forums. That is why they have a CS department.

As for the steel itself. Well....after many discussions and phone calls to a metallurgist due to carbides forming in steels certain carbides actually act negatively and can start chipping out. That is why S30V had some issues when it was pushed to higher hardness (there were many complaints about S30V chipping in the native until the issue was resolved). High carbides are good for certain things, not always for knives. Bog carbides are not good for low angles. One can see this in Ankersons tests. High carbide volume steels are performing better for those applications and he applies a course edge that works great with carbides.

Some steel manufacturers feel that the optimal vanadium carbide in steel is .2%. Why do they make knife steels with higher carbide content? Because we the public want it and therefore they make it.

All my CRK's have come with a (slightly) convex edge, so assuming that's true in general, that would explain why you guys have different measurements of the factory edge angle. Where you choose as the tangent to the curved (convex) edge will influence the measurement.

this video was a cut test he did by request by not only me but alot of people on his channel. Your supposed knowledge is wrong. He does the exact test with all of his knives and none of them failed this bad. He has nothing against chris reeves knives, he was just testing to test the edge retention. This video was never meant to end up on blade forums to bash Mr.Reeves knives. Theres a reason he was not the thread starter. He was respecting Mr. Reeve wants by not posting on the forums. He doesnt control others actions. As for me im not trying to start anything with you i just think that before posting the facts should be correct.

Btw this thread should just be closed down by the mods theres Too many fan boys here!

If you're hinting that a prevous problem with CRK would cause CTS to make a video and purposefully flaw the results or stack the deck to make it appear that his Sebenza was fine but bent under the easy task of cutting some rope, then you don't know people very well. CrimsonTideShooter is a straight shooter and not some underhanded jerk who would go to such lengths for the purpose of revenge or making CRK look bad. I hope I've misunderstood the posts you guys made.

I'm most certainly not one of them!

dont worry cziv this post was not directed to you. I know who the logical ones are here

 

[CrimsonTideShooter]

My sebenza, (none of them, actually) have come anywhere close to 30 degrees. More like lower 40s near the heel, and almost 50 near the tip.


As for you thinking I have some agenda, give me a fucking break. You think I thought up this test months ago just so I can bash CRK in the future? I bet you buy into all the conspiracy theories too.

If I hated CRK and wanted to talk shit, then why would I keep buying their knives, and praise them multiple times in my vids? You don't even know how ignorant your post was.


And you think I was using "all my weight?" They were slicing cuts, how exactly am I using all my weight? If I were doing push cuts, then sure. Ok, I'll play. You say that you aren't surprised that the knife deformed; why didn't the other 18 I tested do the same thing. Also, you say "harder knives break." Well then, why didn't the ZDP-198 Stretch (65hrc) I tested break? It was ground MUCH thinner than the seb, and it held up just fine. You don't know what the hell you're talking about, you just had to jump in because you have some personal problem with me. Pretty pathetic.

Sebenzas come at about 30 degrees, you didn't have to thin it out to get to 42 degrees. If you thinned it out, it would be less than the factory angle.

Thanks. Anyone who thinks I did this on purpose just to diss CRK obviously don't know me very well.

The knife failed, and the fan boys must have a scape goat, because the precious Sebenza can have no faults. It's honestly laughable.

CRK never asked for this video to be private. And also why would I have kept the video private? I made the video for my viewers, they can't see it if I make it private.

Are you trying to say that just because it performed poorly I should have protected CRK and took the video down? That is ridiculous on many levels.

Sorry to say but this is what I was thinking.

 

[ssblood]

From the conversations I have had with CTS people are barking up the wrong tree thinking that a bad experience would cause him to try to make them look bad. Some people have a lot more maturity than that and he is one of them.

I have personally had Chris Reeve call me a liar and I was in the right and it was later even admitted that I was. My Umnumzaan still has the loctite stains under the pivot that would require blasting to remove.

There is a reason Heather answers the phone.

I don't do the fan boy stuff and it is getting to be ridiculous. I love the Umnumzaan and I can look past a makers history and personal business but the CS with CRK that I received and others that I respect is almost to the point of my Umnumzaan being traded towards a SMF CC.

 

[DallasSTB]

I'm assuming that there wasn't a preexisting condition and this deformation occurred during the test as shown, I would send it back to the shop the very next day. CRK has been producing a lot of knives recently, and a little extra vigilance on the QC front may be warranted. I have confidence that the'll make it right, because right now - it isn't.

 

[Esav Benyamin]

This right here are wise words and I thank you for looking at the big picture. These threads could and should be informational and informative but they most always
turn out to be the opposite. People start taking shots at eachother and at the knifemaker in question. Lets keep this more about providing neutral information and
less about bias opinions. Neutral infor is what I believe CTS was trying to do.

I would like people to keep what you said in mind when they remember this thread.

Unfortunately, we are getting to the point where the vulgarity is out of hand. I am not going to ignore it, and I am not going go through post after post to delete it.

This thread is closed.
