Another Leek TIZDP189 with odd sharpening angle.

What exactly caused the break?

What exactly caused the break?

Eating, hard plate.

Unless it was a vigerous stab, such contacts should just indent the steel.

Just normal eating I dont use my knives as axes in my plate, I'm beyond frustration now.

I'll take it to the backstand tommorrow, I'll curve the back of the blade to join the tip, less pointy more solid.

That is understandable, you may want to consider contacting Kershaw, living in Canada myself I realize that you may not want to go back and forth through customs, but there is still the ability that they might be able to offer you some satisfication - plus every vocal complaint helps to put pressure to reduce QC concerns and effect design change.

oufti, seeing that picture I think you have every right to be upset. That edge is so obtuse, if I didn't know that was a picture of a knife blade, I would assume it was some kind of garden tool or something.

Not to fuel your anger, but seeing that makes me wonder if Kershaw didn't know just how brittle the steel in these blades was (maybe a particular batch) and made the edge obtuse like that on purpose, knowing they wouldn't hold up if made more acute.

Is the pic from before or after the reprofile?

I did write to warranty dep. in fact, but before the break, just to notice them about the dull edge, not asking for anything.

Now I dont know, I dont want to send it.

In the picture the edge is up, it was the beter picture I had.

I'm not angry, sh*t happens, but I tend to agree with you on this particular element.

After reprofiling, which of course had the tip thinner, but not much in fact.

I just received an answer from Thomas W. to my email, the most important thing is:

Please forward me your shipping info, and I will ship you a new knife.

I may be somewhat frustrating, but such a service will lighten my MONTH !

Kershaw rules !

BOUHOUHOUHOUHOUUUUUUUUUUUUUUUUUUUUUUUUUUUUU...

The Sauerkraut was too hard...

exact thing happend to mine preparing vegetables in a wood cutting board, tip just snapped right off. :grumpy:

 

[severedthumbs]

here is picture of reprofiled tip, noe blade is so short the safety is useless.:grumpy:

I feel I should stick up for Kershaw a little...

Outfi, if you had contacted Kershaw first, you would have gotten a new knife and saved yourself all the trouble of posting pics and creating new posts. Thomas would have sent you a new knife even without your posts here. And Thomas W had already stated in previous posts that the ZDP project would have been better on another blade shape than the Leek's. I think the ZDP Bump or ZDP Cyclone will yield much better results.

Enough with all the ZDP Leek bashing! If you don't like them, contact Kershaw directly (as there is no Kershaw rep on the BF anymore), or send them to me for safe keeping !

I know Outfi was reluctant to fight customs again, but there is no reason for someone in the US not to give Kershaw the opportunity to make things right.

Since when is Bladeforums simply about praising knives, reporting of problems is just as important.

Did he get more accomplished complaining to us or Kershaw? I think the forums is great when you have an unresolved issue, but far too few people praise when something is good, compared to how many people complain when something is bad. I just try to equal that out. I am glad outfi is happy now. Maybe by his posting, more people will realize what a great Customer Service Dept. Kershaw has.

 

[severedthumbs]

he is making others aware of a potential problem to look out for.

 

[Cliff Stamp]

I noted twice in the above he should contact Kershaw, however I would not extend this to not posting about the problem at all. I appreciate the information for reasons severedthumbs noted.

Us. He let us know that there was an issue with this knife, and many others have done so with this particular model. Thomas seems to be very correct, the Leek was the wrong one for this particular experiment. I would like them to give the Cyclone a try, with the same steel and handle/lock treatment.

 

[Cliff Stamp]

I think the Leek is sort of ideal for ZDP-189, isn't it supposed to be a light, precision, gentleman type folder?

-Cliff

I think it's an issue of their combination of multiple grinds for the look of the Leek blade, combined with them switching to a flat grind from hollow, and the thickness of the stock they used. Doing this and not getting the people who sharpen the knives fully acquainted with this model seems to have led to the problems with dull blades oob. I'd like to see the mini Cyclone fully flat ground and thinner behind the edge than the zdp Leek. And the tip might last a bit longer.

 

[Cliff Stamp]

The thing about breaks and thickness is that when you grind thinner you tend to see more deflection because everything gets very flexible when it is very thin because the stress under a given bend is lowered. I would not be surprised if a very thin tip was squat when impacting off of a plate as that is similar to grinding into a sharpening stone, but I would not expect a casual contact to break off a piece of the tip.

Interesting comments about the grind. However the edge angle is reported to be very high which would seem to be independent of the nature of the primary grind. Some of the ones cited are so large that it would take a visible difference in height of the blade away from the belt, you would see if just watching someone for example. I'd also in general like to see the R&D departement not use the user base as an extended test group, all of these issues should be worked out in house. Take some prototypes and expose them to a battery of cutting tests and then accidental abuses and make sure the responce is within expected tolerance. Similar with sharpening, do random spot checks on the line.

However it is nice to see someone other than Spyderco experimenting with such steels, competition is always a good thing for the people buying the knives. I'd like to see some high cutting non-stainless steels as well though similar to O7 class steels.
