Can't see it that well on my phone. Might be an overgrind. What brand of knife is it?
My new Shigefusa Looks like it is about 4mm long by maybe 0.3mm tall.
It's probably a welding flaw or a split from heat treating.
I can't see any detail.
look for the split on the edge right of center.
Looks like an overgrind to me but it is not clear. Can we get some more angles?
Looks almost like delamination, but its down past the cladding. Maybe some type of impurity in the steel?
For anyone trying to get a better view (and using a pc), you can right click on the image and pick "open in new tab"
Then hold down ctrl on the keyboard and scroll your mouse wheel to enlarge the image.
