San Mai VS 3V - Tai Pan?

[jux t]

So HT is a wash if that's the case.

Is there something I don’t know about Peters’ heat treats? Thought they were considered consistent.

Yes, that's why I said it's a wash. Meaning that you are getting a good standard ht in 3v.

They used to test at 60+ on the Master Hunters and I think 58+ to 60 on longer knives. Pretty decent hardness and you know it’s actually CPM-3V (not just 3V).

Edit: maybe considering something a wash means different things to people of different regions.

I use the term cpm3V and 3V as the same. You apparently don't. So please tell me what 3V is, if it isn't cpm3V.? I am interested in finding out what sets them apart as I did not know there was another steel called 3V.

It's a wash -- "idiom. used to say that something is equal and that one side does not have an advantage." meaning, heat treat is good on both steels. So yes, you did not understand the way I used the idiom.

Is there an ingot version of 3V besides the power metal CPM 3V?

Yes, the original steel with the same chemical composition existed prior to cpm. But I am pretty sure that the only version out there these days is cpm. Maybe I am wrong. When someone on the forum says 3V, 99.999% of the time they mean cpm3v

This makes it sound like it should all be powdered CPM:

The History of 3V, Cru-Wear, and Z-Tuff Steel - Knife Steel Nerds

A whole series of knife steels have one ancestor to look to - Vasco Die, a 1960's era steel that inspired metallurgists for decades.

knifesteelnerds.com

"Therefore they pursued a patent on powder metallurgy Vasco Die steel, and called it CPM 3V. It is a bit surprising to me that they successfully patented a powder metallurgy version of a previously patented conventionally produced steel from another company."

Not claiming to be correct. I find the more I learn about the various steels the more questions I have.

It is also possible that the patent ran out. Quite often a patent is obtained well before a product comes into the market, so that patent could have been much older.

Tried looking it up and don't see a CPM 3V patent expiration date. Did find where many patents expire after about twenty years.

But I did see where 3V is copyrighted:

::Crucible Industries:: Our History

So no one should be able to say 3V unless it's blessed by Crucible.

Yeah, I think you’re right on both accounts. My apologies. I had it in my head that a wash had a negative connotation.

Quick update on this older thread. That place that rhymes with ridgebay finally got Tai Pans back in and put them on sale for $129.99, but today I checked and they had a special offer discount that took off another 25%! So new San Mai Tai Pan on the way. $114.99 shipped! Can't beat that with a stick. I will give a report back on the QC and overall execution of the knife once I get it in hand. Thank you all who replied on the steel question. Also I have been looking on ebay for custom sheaths for the Tai Pan. There are quite a few that look good.
