I need help to repair my sebenza!

I messed it up – I will fix it (if possible)!

But when I try the blade keeps one breaking down.

Please advise me.

This is my equipment:
Spyderco Tri-angle Sharpmaker
Lansky sharpening system

Thanks in advance

I e-mailed CRK:


Subject: Why is my SeBenZa all torn up like this?

Hi CRK!

I need help her!

I use the corner of the medium stone and the blade looks like this:

I use Spyderco Sharpmaker.

Hi Thomas:

I am so sorry to see how bad your blade has chipped out on you - this is
not good at all. I believe the first problem came from the Sterling
Sharpener you used and then when you ran it on the Spyderco Sharpener
this made it even worse due to there already being a problem with the
edge....

Is there anyway you can ship the knife back to us and then I can get the
guys to get this fixed right away and back to you?

Please let me know at your convenience and I am terribly sorry for any
inconvenience this may cause....
Sincerely,
Bridget
 
Thomas,
I think the ideal solution would be to send your knife back to CRK. If this is not possible, I dont see why reprofiling on your sharpmaker or lansky would not fix it. Although, faulty heat treatment may be possible I doubt this is the case. It just seems that your sterling sharpening messed the edge up.

Good luck.
 
send it back to CRK. you will get a flawless blade back. the sterling sharpener probably chipped the blade because there was an angle between the blade and the edges of the stones on that sharpener which caused small amounts of binding. that couples with just a LITTLE bit of pressure can result on large torque loads on the VERY small are that was trapped, and cancrack/chip/rip that metal off. i am sure CRK can get u a flawless blade abck in no time.
 
Danish Viking, is the reason you have not send it back yet because of the current Danish knife-laws?

Ted I meant every word of this:
“I messed it up – I will fix it”

If I can’t maintain the knife at home I can’t do it in the mud.

And it’s in the mud the knife is important to me.

But you right – The (stupid) Danish law forbids me to own this knife.

DanishViking: Could you give me some info about danish knife laws? Maybe I take a journey there and do not like to part with my knife ...
 
Send it back to CRK. I had the same attitude. I scratched my large regular and didn't want to hassle sending it back. In the process of trying to fix it I messed it up really bad. So bad in fact it was unrepairable and I needed to get a new blade. Send it back and get it fixed right. Had I sent mine back it would have been a simple inexpensive fix. But because I had to do it my way, the blade was ruined and it cost $150 to get it replaced.

Are you handy enough to remove the thumb lug, send the knife to CRK for repair, then re-install the thumb lug when they send you back your legal (not one-handed opening) Sebenza?
 
Maybe send the knife and handle back in two seperate packages, have them do the same for you.
OR
Get some 100 grit sandpaper and tape it to your sharpmaker rods. Have the flat side of the rods facing eachother when you do this. Use moderate pressure and the same motion you would when doing regular sharpening. You will need to do this with the sandpaper until the chipping has completely been ground out. Then sharpen on the sharpmaker as usual. The hardest part is not being afraid to mess up your knife. It is going to take a few hours. If you get frustrated and get the "want it done now" feeling put it away and go at it again another day. If you are fairly good at using the sharpmaker you can fix it.
 
I choose to do as adviced!

I am sending the blade back to CRK.

I think this is the best in the long run.

The answer from CRK:

Hi Thomas:

With the blade being so chipped out on the edge it would almost be in
possible for you to fix it yourself at it could only make it worse. Do
you know of anyone local that does sharpening? If so you can check with
them to see if they can help you fix the edge.

If you would like to send just the blade back into us this is just fine.
I wanted to also have the guys check the hardness of this blade as we do
that with any knives that come back chipped. Then I will have the guys
get it on one of the grinding belt and get it re-shaped and sharpened
for you.

Please let me know if this will be alright to send blade back to us or
if you would prefer to try and find someone local.
Thank you Thomas!
Sincerely,
Bridget

That isn't a serious edge issue, assuming you want to actually use the Sebenza as a work knife if such a problem was impossible for the user to fix the knife would be rather useless. All you need to do is grind a new bevel on the edge, I would use an x-coarse hone or some sandpaper to grind the new edge. There is no need for care in the angle, you are just doing a rough shaping to remove the damage. Once you can't see the chips then just apply a secondary edge bevel with the Sharpmaker.
