Here's the tip of an Extraction Unit 17, not sure what unit it was extracting when it suffered this deformation, although I've done this <and worse> on my own before, I was not the operator 
in this particular instance...
note the characteristic edge deformation...it's what INFI does when it contacts "harder than INFI" under a substantial force
:
I call this shot "the unicorn" :
I started with "steeling" the edge with my old soft screwdriver shaft...
Then moved on to Spyderco med. benchstone...
Then Spyderco white rods...
got it to this point <literally>:
edge on, I noticed under extreme iPhone magnification some light still reflecting back at me from the apex:
back to the fine Sharpmaker rods with the following results, better, but still not there:
better yet, I pushed the little burr a bit more distally toward the tip:
this is where I stopped... the black blob is mildew schmutz left over from where I stabbed my deck post for the last pic below :
just the tip, pretty clean profile :
I'm gonna strop her with green compound tonite after supper, but even withholding that, the point is now the keenest part of the edge.
I can't say it enough >>> how much I love the way INFI grinds with ceramic, it's a very satisfying sensation, I'd compare it to carving the Easter ham.
I did all that with just barely darkening my white Sharpmaker rods and leaving a few gray streaks on the medium benchstone...I feel like I really was able to conserve a lot of steel after re-adusting the apex...that's not been my experience with just any old steel.
