Uneven grind on Delica ZDP ?

[John E Woven]

I've got a Delica in ZDP189. Great knife, but the grinding on it is uneven. Is this normal, and what can I do about that ? It's much higher on one side than the other.

Sounds Like a green horn sharpened your knife..
You can use a diamond to even out the sides at 30 or 40 degrees..
That is about it. Or send it back. And ask for a new one..
Easy fix, but still stinks...

If it's not making you happy and you don't want to reprofile /sharpen it yourself than send it in. Contact W&R using the instructions that came with the knife provided you bought it new.

How bad is it? That's the question you need to ask yourself. These are sharpened by hand by professional knifemakers in Japan. There is no jig, just experience so there is no "perfect" angle. Just specs that it's either in or out of. Joe

I'm a pretty picky person when it comes to knives, but uneven grinds don't bother me. Unless one side is extremely thin and high and the other is short and obtuse, it's not too big of a deal. I usually find this more on my benchmades and less on my spyderco's though, but it does happen. Just use it, the delica's a great knife.

I have the same knife and the same uneven grind. I don't thinks it's anything to worry about. The grinding on the swedge on my Native is uneven as well ans the saber grind on my Manix 2.

You're good to go.

...Are you talking about the the cutting edge bevel or the saber grind line? I was answering you thinking you were referring to the saber grind line and not the cutting edge line.

A uneven bevel is not always a sharpening issue. On a flat ground and most knives in general the grind per side (main grind of knife) is not always the same. Because the grinding is always in relation to the center line of the knife just like the sharpening even a perfect 15 or 20 deg per side bevel can be uneven. If you look at the plunge line on each side and notice even the slightest of difference this can make the edge bevel of uneven size. Its not something even the best of sharpening jobs can correct and a fact of life we must live with.

This uneveness in the main grind of a knife can also make it look un-centered when closed even though its not

The FRN handled knives that Spyderco produces in ZDP-189 were intended to allow folks to experience a steel normally reserved for fairly expensive knives in a "working folder" at a reasonable price. They are not high end customs, just excellent tools.

Reprofile that sucker and enjoy the excellent slicing ability. I just reprofiled my ZDP Stretch this weekend, I'm set for the week.

It is not unreasonable to expect an even grind on a tool. The grind is what makes it a tool.

Its unreasonable to expect a perfectly even grind unless its a custom. Maybe im ignorant but I dont see how a slightly uneven grind makes any sort of differance in performance.

Every american made knife i purchased from spyderco and benchmade have been near perfect.
Over seas stuff not so much.
My Old Sebbie came with a crappy grind and dull edge too..
You never know.

The saber grind line near the tip of mine is just a bit off on one side. It's a user and doesn't affect the use so I don't mind. Gives it some character and I know it's mine.

 

[John E Woven]

Thanks for the replies.

It's the grind, not the edge. I actually noticed it while sharpening it. It's not a huge deal, I was just wondering what I could do. I'll probably end up just keeping it like this

It's about 2mm higher on one side than the other at the very back of the cutting edge, measured from the top of the saber grind to the top of the spine.

I recently got a Benchmade 942 from a store and the blade grind was ridiculously uneven. I sent it into Benchmade and I am awaiting its arrival. If I were to fix it, I would be removing a decades worth use of metal!
