I was doing some post-ht grinding on knife #8b and the hamon started to pop out. It looks like it may be a bit too close to the edge. I did a quick polish/etch to one side and snapped a photo.

What do you think. Am I hosed? At this point, I think the edge is too thin to re-ht successfully. :(

Yes. :)

Personally, I think it's too close, but with the work you have done, and the story that goes along with the knives, I think you should finish it out Erin. Besides, it looks like you've got a lot of great activity in there.

This is why I run a blade over a 60X belt right after heat-treat and shine the blade under a good overhead lamp so I can see where the line is BEFORE all that fancy grinding and sanding. :)
 
It is a little close for my tastes... However Like Nick say's your gonna be fine for this one. next time you know to find out where it is before ya start grinding overall GREAT JOB THOUGH!

It looks good to me. Could you explain the problem a bit more in depth for us ultranoobs? Thanks!

Mr. Bad...

The soft side of the hamon (pearlite) is closer to the edge of the blade than I would like... especially about 2/5 from the tip.

Its fine.There is at least a 1/4" of hardened steel at the edge.Thats a lot of sharpening before you run into a soft spot.Do aim higher up next time though.

PS great looking hamon.
 
It is a tad closer in some spots than I would have wanted it placed, but with a hamon, you are never in total control. I would proceed as it is. It does look like a good hamon.

Do you think you could draw some pretty arrows and make them neon orange for the ultra noob here too? Ive seen definitions of this stuff, but not a single picture showing how to ID it.
 
Put some handle material on it that's fancy enough that you can be pretty certain that it will see very little or no actual use and you're golden. :p

The red arrows represent where the pearlite is too close to the edge.Ideally you want 1/3 or 2/5 of the edge hardened.
There is some picture tutorialson doing hamons,the best way is to experiment.Take some pics with the clay on the blades before heat treat and compare them to your finished hamon.Different blade profiles and the thickness of the clay make a big difference.

I would keep going on that blade too...
