I’ve been using the 1/8” stock for a few of my more tactical offerings as well as a few hunters. Roughed out a test blank and have been beating the crap out of it. Very impressed so far.

Interesting....the medium thickness they offer?

Nominal 1/8" is actually around.136"?

It's been a couple months since these were released...? Right?
I ordered the first week out, I think? But just now am starting to grind on them
I bought the 3 different thickness and they are behaving differently.

Details/update
I purchased the three different thickness from Pops. I believe it was the first week offered.
Listed as 3/32", 1/8", and 3/16"

I have Bos professionally treat to 62HRC.
I have the dimples from their testing on my blanks. I believe they test every blank.

What I'm experiencing looks like delaminating. It's happening while grinding. I haven't put an actual edge yet on these 3/16" blanks.
It looks like the material is flaking off. At approx. .050"- .070" deep. In numerous locations.





It does appear that I can grind through that failed area to clean up that edge. I have had at least four areas affected like this. Obviously these blanks are flawed somehow.
I tried multiple blanks from this bar with same results (3/16)

I tried 1 blank from the 3/32". That hasn't happened yet.

I tried 1 blank from the 1/8" material and it is flaking apart.

I'm Not blaming anyone,but I'm curious if other people are experiencing other or similar issues...?

Ive heard some things, but I don't want to post rumors. This is what I'm seeing first hand.


Pops contacted me quickly this morning. I appreciate that. They said this is the first They are hearing of any issues, questioning the heat treatment?
I will reach out to Bos as well. Hopefully Larrin worked with them, as he did with Magnacut.

Anyone else know what this is, or have ideas?
Thanks.

Yes, right around .136”. It has been a few months, my steel was from first batch. I haven’t experienced anything like you’re showing above with the flaking, but I did notice the steel isn’t a real spark thrower post HT, at least not like other high carbons I’ve worked.
 
I used a 1/8" bar, didn't notice any issues like this? I did my own HT, 1525, quench Parks 50 (and some in AAA), temper (kitchen oven at 325, really around 340-350) and get 62 HRC. I have a 3/32 and 3/16" bar, but haven't used it yet. I do a fair bit of profiling post HT as well, but haven't noticed anything like this year.

People have noted it doesn't spark like other high carbons and I believe it's the tungsten in the steel that lessens the sparks?
 
I've done 1/8" with no issues and should be doing 3/16" this weekend. Using ATP641 and AAA with a mid heat range I think was 1575 for 10" with 2x 1hr tempers at 350. But don't hold me to that, I'm not at home. If anything weird comes up I'll post it up.

How close to the sheared edge of the bar is the blade?

Thank you for responding....
Is that something we can tell by looking at it?
I'm not sure I entirely understand your question?

I'll say the profile, especially the edges, I clean up and smooth out with finer grits. I worry about stress risers, so I have the edges pretty nice.

You are asking how close to the edge of the strip of steel My knifes edge was?
Is there a general recommendation for a distance?
 
DevinT said:
No, I was just wondering if that could be the problem.

It could be anything
I'm all ears...

So far my thinnest stock, I haven't seen issues yet....

Heat treatment isn't usually a thickness thing is it?

What about stock thickness.... How do they get thinner metals? Is it all the same melt, but some is just smooched/rolled more?

Just seems weird it's 2 of the three thickness for me
 
Clearly what happened is the quenchant is haunted. The quench tank needs to be exorcised of the bedeviled oil and refilled with something non-haunted.

Also, is the surface of the steel patchy-looking? Why are there like 20 hardness tester marks on one blank? That seems like a lot of poking with the ol' diamond penetrator.

They tend to do a lot... Usually 5-10.
But I agree, I thought it was a bit much. Idk if I can even count That high...ha

That one has at Least 21 dimples
