Well, this is annoying....

Dang!!
Wow. That may not strop out.
Fault during quenching or HT?
foil edge? foiled by the edge?

Not a roll, not a foil.
I will probably never know what happened here.
No signs of rust or oxidation. Just looks like the steel failed right there.
Could have been something in the HT&T.
Could have been from an irregularity in the steel.
Maybe it's because carbon steel burrs are so easy to make and remove. :0)
No, seriously - I am leaning to an imperfection in the steel that didn't get hammered out.
Odd given the source, it's a late issue unmarked SSA.
It's all removed now, the Nani Pro 600x did a great job of eating the steel at just the right rate so I could sneak up on the chipping. Did that with 1 layer of tape. Going to start on the 1k without tape in a minute.

You might be right....maybe with some Crox?
I had a 1/2 hollow torrey crack on me vertically once on a 1k and the crack literally spread out where you could see through it. It was the strangest thing. What's interesting is it almost looks in a macro way what some blades I have been trying to put bevels on have been doing where you need a loupe to see it.
Even better, start with 500 laps on diamond pasted strop. You will get back that crispy edge too.
Yeah, only time I've seen similar is on RSO's. That's a steel flaw. I mean in theory you could probably get a proper razor to do that if you ground it down to <7 degree angle... maybe with some spine leading honing thrown in on top... but yeah. Hopefully it's all good once you're past that.

All good now.

Better than before I am thinking! Well done.All good now.
I am curious, when exactly did it break? I am just wondering how much ‘force’ it took for it to come off.

It was fine in April when I cleaned and oiled it and put it in the top drawer of my razor chest.
Have not used it since then, today is the first day I've looked at it.
So what you see in the first pic happened while it was lying on it's side doing nothing.

Sounds like unresolved stresses that would normally be absent after tempering.
Did it seem to spider web out or was it entirely a lateral crack/?Thing ? Sounds like mfg(temper) flaw but it's interesting it flows the length of the blade. I've seen some weird delamination on old steal blades and generally it seems to be cast steels. I've wondered about this from an old razor cracking in a weird way. I'm not smiting expert but I've always wondered if pouring steel I into a cast from left to right makes a difference from top to bottom.... I've heard with even plaster this can be the case and id imagine something that cycles ions would be a bit more dynamic ... in going to start running a forge soon. I'll either get a an anvil or smelt ore through carbon in a stack to pour into a clay mold dug from the ground. Directional flow matters with magnets and earth's geo magnetism,I could only imagine it'd add to tensile strength, but I don't know. Any insight would be appreciated.
This separation would be something I'd worry about from the toe to heel flow of the molten metal to create the blank of it was casted. Im trying to figure out these processes because I want to make a straight razor and scalpel first when I begin to start running this forge. Small amounts of metal but take a decerning eye to make work.

I didnt investigate, I took the pic above quickly and got it honed right away.
Might have been an inclusion, coulda been a temper issue, maybe both or something else.
