Has anyone ever chipped the edge on their Sebenza?Well,I did.I was cutting a large plastic zip tie that was around a sheet metal fitting and did a little twist and put two small chips in the edge right behind the curved part of blade.I honestly feel that I did not force the knife.Is this to be expected with the BG-42 blade.Would these blades not do so well on a brass rod flex test?
I am baffled because I also had accidentely dropped the knife,point first onto the concrete from about three feet and all that happend was some flatening of the edge and point.I was kinda pround that it took that abuse without too much damage.Now the edge has chipped.Whats going on here?
Thanks

So the blade chipped while being twisted in hard plastic - it never touched the metal? How big are the chips?

I believe the chips had to of happened when it twisted against the metal not the plastic.
There are two of them.They are about 1/16" long and the deepest one is appx 1/64" deep.Thanks for the responce.

Last week I was putting terminals on some of the LAN cable used in the office at work. This is 8 conductor solid core wiring. After cutting through about a dozen times I noticed that the edge near the handle was starting to resemble micro serrations! When I got home, about 10 min. on the Sharpmaker had everything back to normal again. The chipped edge was the factory edge, which is ground quite thin and at what appears to be a very acute angle. I believe the 40 degree edge put on by the Sharpmaker will help to resist chipping in the future. I do not take this as a weakness in the Sebenza, but rather blame myself for using the knife in place of the proper tool. Probably will do it again however, to see if my theory holds water

It's only a mistake if you fail to learn from it!
 
Cat 5 cable is rough on tools, especially solid-core. I went through 3 sets of diagonal pliers in 6 months!

Wire and knives don't seem to mix well to me. I geeked my micra pretty bad cutting one as well. Sad thing is that I had my Wave right there. D'oh!

I too chipped the blade of my lg seb when trying to cut a plastic flower pot off of a plant. I didn't realize that it had a metal edge at the top of the pot. I was sick when I saw the chip on the blade. A few weeks later I was at the NY Custom Knife Show and met Chris Reeve. He examined it and suggested that I send it back for repair. I sent it back and in a few weeks it was returned looking as good as new. In addition to repairing the blade CR also tested the hardness of the blade, put on a new lanyard and cleaned the entire knife to factory new condition. As always 100% satisfied.
 
I chipped the edge of my Sebenza by plunging it through the top of a beer can and twisting it. I was testing the knife to see how durable it was, and I don't know what to think of the results. That's aluminum, fairly soft, and I wouldn't have expected chipping. I'm waiting on my new Sharpmaker to arrive and I'll be putting a new edge. Might try the steeper angle and test again to see what happens. For now, I've got a 5% serrated Sebenza.

Hello,

I like self made serration !

No big deal, this knives are made to be used and abused...

You don't need a razor to cut platic anyway.

I have a little chip on my Sebenza after fumbling on marble floor...

But I have open so many oyster with it and the blade is really neat after that...

Let's do our own serrated Sebenza ! It's like scars !

cheers,
JM

 
Nemo, you sound like a true knife USER!!! Thanks for the post. I'll have to try my small (plain!) Sebenza on some Cape Cod oysters....

No oysters, but the most mundane of tasks for my Large Sebbie is to use the portion of the backside of the blade between the thumbstud and the pivot end to pop beer tops, works great! Probably not too PC among the Sebbie Elite.

Mine goes through hell every day and stands and delivers. It is truly a user's knife, and I cringe every time I hear of the ones that are "Safely tucked away..."

Got my sharpmaker, and man does that thing work nice. I used the medium to try to take the chip out, but to be honest I would have had to take more metal off the rest of the blade than I really wanted to. So I got a nice utility edge (their term?), then finished it up with the fine stones and it is razor sharp. There is just a little serration where the chips are, but I can live with that. It will sharpen out as I use and resharpen the knife. Didn't see making the rest of the blade suffer for one little portion of the blade!

Seriously, I use the knife every day, so it will get a good sharpening at least every couple of weeks.

Take care,

Brandon

I chipped the blade on my Sm Seb while enlarging a hole in plasterboard. Was I mad when that happened! I couldn't believe that "soft" plaster would do that to my knife! I was able to grind out the chips with my Edge-Pro and put the blade back to hair-poppin' sharpness. Guess it just goes to show, use the right tool for the job.

On plaster? Now that's a bit scary. I'd think these blades would take much more abuse than that. I was surprised at the aluminum, but hey, what are you supposed to do when you plunge your $300 knife through a beer can? People already think you're nuts, so they figure you get what you deserve. But plaster? I'd be a bit ticked too...

In reply to SDW, sorry it took so long to respond but this thread has only just been brought to my attention. Let me start out by saying that the cutting edge of any blade will chip out under certain circumstances. Knives are designed to cut - but difficulties arise when a twisting motion happens during cutting into malleable metals like aluminum and mild steel. Nemo is correct – this kind of thing will happen to any knife that has a good, efficient cutting edge. You can prevent this by increasing the angle – but then the edge does not cut as well. All cutting tools are a compromise between hardness and toughness and BG42 is one of the very best at both. The brass bar test has been done on numerous occasions and BG42 passes every time. There are, however, variations do occur from time to time in the steel and heat treatment - nothing is perfect in this life! I suggest sending the knife back to us – we will test the blade and, if necessary, replace it. Otherwise, we will put back the original – exceptional - edge for you.

Again, I want to reiterate that if there is a problem with our product, either perceived or real, talk to us about it and let us take care of it. We are not perfect but will try to make sure that you have as perfect a knife as is possible.

It sounds like there are some others that have had their edges chipped.My edge chipped with the Sharpmaker angle.I don't really feel that there is anything wrong with my blade.I put it in a tough situation.The chips will sharpen out in time.I like the way it cuts.The Sebenza truely holds an outstanding edge.This thing CUTS!and thats what I'm after.Thanks.

Hoodoo

The low, hoarse purr of the whirling stone—the light-press’d blade,
Diffusing, dropping, sideways-darting, in tiny showers of gold,
Sparkles from the wheel.

Believe me, I am more than happy with the edge on my blade. It sharpened up so nice that I didn't even worry about the chips. Just wanted to make sure I didn't need to worry. The plaster board thing though, I'd probably send it back to have it checked. Just my opinion.

The reason I bought CRK was because I have yet to hear one single comment in the negative about CRK standing behind their product. The reason I can't put my CRK down most of the time is because of the sheer perfection this knife represents. Let me go on record as saying that if CRK ever decides to exit the knife business I will be forced to hunt you down and pester you until you change your minds.

Waiting to become a CRK stalker I remain...
