I just picked up a N.I.C.A Tanto with BG-42 steel blade. I was slicing the bark off a walking stick and when I went to put it back in my pocket, to my horror, I saw that some of the blade was missing !!! I found the blade pieces, they were crumbled and looked like grains of sand. I already emailed CRK, but I will probably not hear from them until Monday, and I know it should be covered under warrenty. But I would like to know if any of you out there have ever had any similar problems. I just think it was a bad blade or poor heat treat. I love the tanto style, thats why I got it. The blade definately needs replaced as a regrind will not fix this as it is at least 1/8 up into the blade. I was and still am shocked.

Horrible to have that happen - but I cannot help but say that it looks like you have the beginnings of a serrated blade! :p
 
Me too. I have the same knife and I've used it harder than I have my drop point Sebenza. Not a problem. Both of mine are BG-42 and I've sharpened both a few times.
 
The only thing I can think of is that it has a bad blade or poor heat treat because all I was doing was slicing bark off a dead branch to make a walking stick. The knife looks like it should be more durable than the drop point.
 
I'm sure CRK will take care of you! Their service after the sale is the best!
 
that sucks twice.

once, because it happened.
twice, because they will probably have to replace it with an s30v blade. :(
 
I know I asked Heather before that I wanted a tanto blade and she stated they were a special run and one could not be made for me. I then asked her if I had a tanto blade and it was damaged what would they do and she stated if a tanto blade needed to be replaced, it would be replaced with a tanto blade.........How ironic. I asked her that last Fall. I just got this Tanto Sebbie on Monday. Now my weekend is going to suck :( The worst part like you said is its probably going to be replaced with a S30V blade. There goes the collector value !!!....lol Maybe its better, this one with BG-42 did not hold up too well.
 
Looks like they made it way too hard...to the point of brittleness. I'm sure replacing that blade will be NO PROBLEM :D. Thanks for sharing the pic! That's way cool :p
 
WOW, and i was thinking of getting one of these, maybe yours is a lemon. However now i will just wait!!!!!!!!!!!!
 
could very well be the heat treat. :confused:

or there could have been an unoticed fracture from prior use.

you bought it used, correct?
 
IDK man, I wouldn't be too worried about the S30V. I've been living with it for a while in Large Regular and Large Tanto flavors, and it seems to work just fine. I think it actually strops up better than my BG Sebenza.

Also, never had anything like your photo. Would imagine that's bad heat treat.
 
I believe it to be a bad heat treat as well. It happens !!! I like the S30V and find nothing wrong with it at all. Its just that if they have to put a S30V in the originally BG-42 tanto, it lost much of its collectibility

I did continue to use it on the branch after the pieces crumbled. It performed like you would expect it should with no furter damage. I did get it pre owned, possible it had a small invisible stress fracture from the original owner.

Click to expand...

The Sebenzas are Great Knives, I have 5 others and have had no blade problems and I have used them. I believe it was just a bad blade that got through, poor heat treat or possiblely a small invisible stress crack from the previous owner. Dont let this one stop you from getting a sebbie. I know I will certainly buy more. Its just a rare fluke.
 
I hear a lot of people talk about steeling a rolled edge, which seems like a bad idea IMO :confused:, perhaps the PO had done that. Just a thought.
 
ive steeled out many edge rolls. ie, no steel from the edge is missing, just dented and pushed to the side.

why do you think it a bad idea?
 
Rolled edges are what steeling is for. Just slide it down the steel and you won't harm the edge. it's less destructive than sharpening because it doesn't remove metal from the blade.
 
From what I've heard, haven't really done much steeling, one uses a steel to realign an edge during prolonged use, i.e. butcher shop, to prevent the edge from actually rolling. Pushing a rolled edge back into place may save some steel in the short term, I just wouldn't trust the edge to be as robust, like bending a paper clip, it gets weaker each time. The few times this has happened to me, I just lop it off and grind it down.
