What are these lines in my INFI? Stress cracks?

Just got my BAD off the market here today, it appears to be completely unused with the factory edge, but under just the right light I'm noticing a lot of lines that run parallel to the edge. As in, against the grind.

I took several pictures and these two are the only ones that I could get the lines to show up in. Is this just something that happens when INFI is hardened up to 60-62RC? Or is this something I should be concerned about?

I'll admit, I'm a new hog. This is only my second Busse (but the third is coming soon, hopefully. ;) ). But of my very limited experience, this is my first time seeing lines like these.

EDIT: Answered by Jerry later in the thread, these lines are a grain that is created when the steel is rolled in the mill (see post #20).

That's just the INFI. Nothing to worry about :thumbup:
Now go use that beauty :D
 
Nah, nothing to worry about, that is the standard satin look. Sometimes it is vertical, sometimes horizontal, sometimes both. I don't know exactly what it is, but it always looks to me like something they brush on as the final treatment for the satin finish that definitely has a grain/texture to it. From my experience, it's also the first thing to disappear with use. ;) Enjoy that little slicer! :p
 
I was really hoping that. It's worth feeling like a bald-faced beginner to get a little peace of mind. :D
 
they dont know what they are talking about, its a factory 2nd. Ill give ya $150 for it if you ever want to part with that use-less thing :foot::D
 
I've seen that on some of my satin Busse's as well. I remember I first noticed it right after using a Tough Cloth on one. Did you use a lubricant on it prior to taking the pictures? I beleive that is all it is.
 
I've seen one like that before. It kind of looks like an old chrome bumper after the chrome starts cracking but it never cracks.

I wouldn't worry about it. Just use it. Should it fail, Jerry has you covered.

That is a sweet blade! BAD's are really cool EDC's.
 
See that all the time on stainless steel knives with a similar finish from other manufacturers (including custom knives). In fact I think I've seen it on most of them. Nothing to worry about.
 
It's gonna spend some time on the Edgepro this afternoon, then I gotta find a sheath for it. ;)

I have a coyote BAD w/satin finish and have the same lines. I was also wondering about it.

Thanks for posting.

Same here-didn't notice it till after a Tuf Cloth wipe down. Didn't think about it till this thread. Don't think it's anything of worry though!:D
 
I have actually seen similar lines on a lot of satin knives, not just the BAD.

All the BADs llok like that. I think it's due to the higher hardness. :confused:

I was guessing (and hoping) that. Still nice and easy to sharpen up... and I've owned it all of 24 hours and it's already drawn blood! It touched my finger so lightly that I didn't even notice it, but it split skin and feels like a papercut. ;)
 
Been told by my guys at the mill that what you are seeing is the "Grain" of the steel that is formed during mono-directional rolling. :thumbup:

Our tests have shown that this adds to the lateral strength of the steel.

So, what you are seeing is a Good Thing!!! :thumbup:

Jerry :D
