Pic Request - battle damage on blades

[vajo]

John i thought Kirikomi are only possible in the mune. Kirikomi "cut" is working because the harder cutting edge cuts into the weaker mune.

 

But this looks like a cut into the very hard cuttings edge? And is it a kirikomi or a fatal flaw because it is going through the temper.

It's surprising how many blades have been damaged by bullets during WW2, it makes me wonder, are there any pictures of older blades damaged by Teppo ?

WWII = full auto on the battlefield, lots of bullets, lots of hits.

A sword I recently acquired has damage to the ha, muni and ji.  Most of the damage is from the middle of the blade increasing out to the kissaki.  Of these, a straight cut in the ji with a very steep V cross section is the most intriguing.  I don't think this is the result of bushwhacking.  The maximum depth were it terminates at the shinogi is ~0.3 mm.  It's maximum width at the shinogi is ~0.4 mm.  It's length is 6 mm.  A distinctive splatter pattern of fine rust on both sides of the blade radiates from the ji.  

 

As a complete beginner, I am trying to learn the names of the sword elements so please forgive me if I have mislabeled anything.

 

I inspected a sword at the recent Japan Art Expo with a very similar indentation described as kirikomi, and in a similar part of the blade, about halfway along. It was over a cm in length with quite a jagged appearance
