Tiny chips, keep or grind em?

So, found the first chips on my new Kohetsu Aogami Super Gyuto after two weeks of use in the kitchen. Guess stuff like that happens, regardless of how careful one is. So I'm definitely not in a panic mode.

But I do have a question about chips: Do you grind them out on the stone and reset the whole bevel right away, no matter how small & deep they are. Or does it depend on the size and the location of the chip?

I mean I've seen horrible chips, where people wedged their blades or dropped them on the kitchen floor, in which case there is really no reason not to grind them out purposely. Mine on the hand are really small and shallow, it's hard to pick them out without magnification(at least with my average to bad eyesight...I'm a four eyed guy). There are only two chips, sitting less than an inch apart from each other on the curve part on the blade and they are maybe a hairline deep. I guess got them from some leftover dirt/sand when I used the blade to slice-cut some vegis last weekend. I've no indication so far that they interfere with my cutting, esp. given that they are nowhere near the sweet spot for push-cutting (the technique I usually use) on that knife.

The "OOTB-Edge" itself is still quite sharp (cuts through tomatoes and thin newspaper like air), so I'm curious if there is any good reason for not to wait until the edge dulls. Given their size I think they would go away the first time I resharpen the knife anyway (I can try to take some pictures, but I can't guarantee that they will turn out well...). Which is what I would prefer, because I want to see how long the OOTB edge lasts...

Cheers,

Especially in a user kitchen knife, I would just leave them. When the knife gets dull, then I would sharpen them out. There is not a reason to wear down the blade as long as it is still serving your needs right now. Most of the kitchen knives in my house are chipped because my wife is not particularly careful whith the way they are handled or used. However, they work just fine so I just keep them sharp for her and ignore the chips:thumbup:
 
It sounds like the chips are small enough that you'll get most of them out with normal sharpening.
 
You basically answered your own question:
- Waiting for OOB edge to last. This is something you won't have it back, because any sharpening you do will change it (might be for better though).
- The chip is not in the way of your cutting, and not causing hiccups in any normal use

I'd say wait ...
 
I have a few knives that developed micro chips that weren't visible to the naked eye. Since the entire edge was good, I figured it was a good time to experiment with consistency while stropping and tinker around with different uses of black compound. The end result is the best edge I have ever done, with no micro chips, and my technique is a lot better too.

Find a day you are free and make a day of it. Just make it a day for maintenance on all of your knives. No matter how good your technique is, you can always improve or inadvertently discover something new.
