Another Leek TIZDP189 with odd sharpening angle.

I wanted this one so bad... I read about sharpening angle on this particular model of leek being sometimes very odd, I was hoping to get through...

Well, not. After more than 1 month wait delivery (Belgian customs are slow...) and 70% of income taxes I finally got my leek.

It's a wonderfull knife, light, beautifully constructed but with an edge angle between 50 and 60 degrees it's quite deceiving for a such high end knife, that's the first time I put so much money for what I thought would become my new permanent edc. Well, not.

I know Kershaw has a wonderfull after sale service, but I dont want to let it travel twice oversea with the problems I already got to have one here.

I could have put it on my backstand to put a more correct edge but didnt dare to do so, it's not like it was one of my XC75 piece of metal I would not be too sorry if I miss the edging...

So I passed some hours on the sharpmaker trying to put some decent angle on it and the result is... well...

So, I'm quite sad about my purchase :(
 
Sorry to hear about your unhappy experience!

You may want to consider something that has higher grit than the Sharpmaker brown rods - such as coarse DMT stones. If you don't want to free-hand sharpen, get some low grit wet/dry sandpaper (200-400 grit) which you can wrap around the Sharpmaker sticks. You'll remove a lot of metal quicker than it'd take for hours of work on just the brown Sharpmaker stones. You'll want to use the sandpaper until you can cleanly cut newsprint before moving up to the brown Sharpmaker stone corners.

It really is sad to receive a new wanted knife and have edge angles that are acceptable. I am the sort that tends to resharpen immediately when I buy a user anyways, so I usually look forward to the challenge.

Best of luck.

Intersting way of thinking, you'll sure never be deceived by a knife this way :D

For the Diamond stones, it's kin of out budget right now (the leek was already out of my budget...)
But i'll give a try at the sand paper wrapped to the stones, thanks for the tip !.

I love you ! (well, in a friendly way, huh !)

What's dumb is that I already recommand this method to someone to put an edge in the first place to a knife he just did... I never thought at that solution for me...

Well, so, 3 times 2 pieces of water 400 then like usual, medium than fine rods and the leek is shaving like a true razor ! I have to stop now or I wont have any arm hair to test my knives... :D

Ok, I'm happy now, but still feel a bit unhappy by the fact I had to do this to a factory knife to have something that cut, I wonder what happened back there.

It is much faster to sharpen a knife on a very obtuse angle, especially if you have a hard to grind steel like ZDP-189. You might also want to consider a complaint to Kershaw directly.

mine was 28degrees per side. I thought it was ridiculous so I broke out the diamond stones and reprofiled it to 13degree per side, this made the tip much to fragile for my uses so i also reprofiled the tip to make it stronger. It is a much better slicer now.

What's the point of quick sharpening a knife that dont cut ?

What do you want them to do for me as I dont want to send it oversea ?

I've made it the classical way for my sharpmaker, 30° back bevel and a 40° edge it's perfect for me.

It is cheaper.

It is just to note a problem, if enough people complain then it can induce pressure to tighten quality control. Just email them and link to this thread so they are aware it is being publically discussed on a heavy traffic BB.

Ok, I understand.

But I think they are aware of the problem, ThomasW from Kershaw is quite often here reading and answering kershaw related thread and everyone agreed they have a wonderull after sales service, a friend just received a bunch of things from them as he was just asking a torsion bar for his scallion, great service !
 
I read through an older thread about the zdp leek, and it was already full of complaints about the dull blades. They were made in a couple batches, so hopefully the new ones are sharpened properly. What surprised me is what a floor manager said-the zdp is thicker behind the edge than the other leeks, by 0.004". I had thought about getting one, but it seems it would have been better with a full flat or the typical hollow grind that leeks usually get.
 
ZDP-189 is difficult to machine/grind and then might have been concerned about damage so it isn't unexpected they left it thicker.

Well, it just seems a little backwards to go with a high priced steel at 64-65 Rc, just to have to leave it thicker than standard models because you're worried about chipping. You could just thin out the 440A, hone more often, but repair damage far less.

It isn't backward if you look at the sales figures, ZDP-189 can likely sell on name alone, but I would not contend your point regarding functionality.

Yeah, ironically the higher cutting ability of a thinner 440A edge would not only extend the cutting lifetime as a more optimal profile will cut better at given sharpness but it would also be easier to sharpen because there edge isn't as wide. In general, from the point of user functionality, if you have to thicken the edge to use a particular steel it is usually a bad idea.

Man I have to learn more about sharpening . . .got any links that will help a newbie understand how to better sharpen and understand the meanings behind bevels, grinds and such?

Thanks . . knida lazy to use the search a sift method.
