It’s a 18th Century Japanese tantō (dagger). Probably too historically precious for an EDC although it would cut open Amazon parcels very well
What is EDC folding knives for?

Ha ha, with all the weight, I won't be surprised it'd cut the skull open quite well.
How heavy is that? 20oz?
In America, an many of men carry clip folders. When we’re out at clubs or small music venues I see clips in many front pockets. Why take a knife to a music club? Handyman work? lol.
I was at a Big 5 sporting goods store looking for some camping gear. At the counter they have a knife display and a young gal was looking at knives. I asked her if it was for self defense. She said “yeah, it’s crazy out there!” I asked her if she considered training and what she thought would happen if she ever actually had to use that knife? I suggested good self defense training and she seemed to agree. I think she bought the spyderco…

You should probably go back and read what I wrote. Because you're completely wrong.Well, look it up, hard and brittle goes together for steel. You might find some exotic metal blades, that' beyond my knowledge.
You live in city and you open carry?

I don't read just what you said, I went on line to research a lot. Get on line, info is out there.

I guess that explains why you're responding to things that were never said. Odd that you don't see the problem with that.

I suggest you to just type "knife edge retention vs brittleness" on yahoo or chrome and read. You really need to get on with time. That's one thing, I am old, but I keep up, I actually learn C++ programming, html web developer, I am the IT of the family, never have to ask anyone to fix my computer. I determine to keep up with the young generation instead of complaining.

Here is the general description, you can read specific website to learn more:
"
Edge retention and brittleness represent an inherent trade-off in metallurgy. To explore specific steel types and their performance ratings, consult Knife Steel Nerds, the definitive industry resource for knifemaking science. [1, 2, 3]
The Core Trade-Off
Enhancing one characteristic of a blade almost always comes at the expense of the other. [1]
- Edge Retention: The blade's ability to resist abrasive wear and maintain its cutting edge over time. This is usually achieved by packing the steel with a high hardness (often \(60+\) HRC) and dense, hard carbides.
- Brittleness: The steel's tendency to crack, chip, or snap under lateral stress or impact. Because high hardness and extreme wear resistance require rigid, brittle crystal structures, maximizing edge retention inherently makes the steel more prone to chipping. [1, 2, 3, 4, 5, 6, 7, 8]
The Two Extremes
- Ultra-High Edge Retention (Maximum Brittleness): Steels like Maximet, Rex 121, or 15V. They have incredible staying power for slicing abrasive materials but are incredibly brittle, meaning they can easily chip if they hit a bone or hard knot in wood.
- Tough / Non-Brittle (Poor Edge Retention): Steels like 14C28N or 420HC. They are highly resistant to chipping or rolling, but they require frequent sharpening under heavy use. [1, 2, 3, 4, 5, 6]
Striking a Balance
Modern powder metallurgy has allowed knifemakers to bridge the gap between toughness and wear resistance. "Super steels" like CPM-MagnaCut, Cru-Wear, or CPM-S35VN are engineered to offer an optimal middle ground—holding an edge significantly longer than standard steels while maintaining enough structural toughness to resist chipping during hard use. [1, 2, 3]

Oh I forgot, in post #68, I copy from the browser, you see there are a lot of numbers in lighter color. You can click on each of them and it will open a new page with article backing what is said up.
This is new age of internet, you get answer on most of the stuffs.
If you are very sure you are right and they are wrong, you might want to look into writing a paper and publish it or even apply for a US patent. It's not as hard as you think. I own 4 US patents on combine electronics and mechanical designs, I also published 2 paper in American Institute of Physics, Review of Scientific Instruments.
Click on those numbers and read.

Lol. Magnacut?
That stuff is trash. Not suitable for a butter knife.
Now we have Magna max. Which is the premium premium super steel.
MagnaMax is an ultra-premium, powder-metallurgy stainless steel designed for high-performance knife blades. Created by Dr. Larrin Thomas (inventor of CPM MagnaCut), it is highly regarded for offering the phenomenal edge retention and wear resistance of non-stainless tool steels (like K390) while maintaining excellent corrosion resistance

Go challenge them, you might be able to publish papers.
You click on all the numbers to read the articles? You are the expert. Or you just close your eyes and say NO?
Click on those numbers, you likely learn something.

I just curious, this is an article for MagnaMax
https://www.bladehq.com/blog/magnamax-steel-everything-you-need-to-know
Read this part in the article:
No steel is perfect, not even MagnaMax. If you’re after a camping or survival knife, or even a hard-use folder, MagnaMax might not have the toughness you’re after. For that I’d recommend its brother MagnaCut, or maybe even a tough carbon steel like Cru-Wear or M4.
Info are out there. I am not an expert, never claim to be expert of steel like you. Just took me 2mins to find this. Get on with the modern world, it's all science.
AND if you disagree, CHALLENGE THEM. IT'S ALL SCIENCE.

I still reading, this is another article on MagnaMax
MagnaMax steel and knife blade construction
Within the page, this is the paragraph:
The trade-off is predictable: MagnaMax does not quite match MagnaCut’s toughness. It is not intended for the most punishing impact tasks or heavy prying, but it remains more than capable within the typical range of folding knives and general-use fixed blades.
This is all science and information is out there IF you care to look.
LEARN, READ.

Sorry Drop Bear
I thought your post was from Dirty Dog. I don't mean to be rude to you. SORRY.
To me, it's NOT about winning or losing a debate, it's about learning. I started the post thinking only about conceal carry, but then I realize there are people that OPEN carry, then I literally change my tune that I see the reason why some want to get fancy knives to open carry. I use common sense to talk, if I am wrong, I am wrong and I learn. But yes, when people attack me( beyond showing I am wrong), I will attack back. Life is fair.
So again, SORRY, this is not meant for you.
Alan

By the way. My post was more of a shot at steel nerds.
By next week there will be mega magna max 2000. And all other steels will be rendered obsolete.

I am no expert in steel, I just read online on how to choose a blade. For me, I don't need the blade to have edge that last forever, just needs to be sharp that one time when I need it. Edge retention is not that important. Also, I think if people that are so into knives, they should learn how to do simple sharpening, that will eliminate the need of expensive blades.
I get used to searching for news and all. I am doing it everyday, I get news even before the cable news like NewsNation start covering it a lot of times. I come here to talk and learn, BUT I do go on other forums and FB to debate politics and world events. I do a lot of research and you'll be surprised how many ignorant people that don't know anything and talk big. I always pull articles from big reputable media to SHUT THEM UP.
Hell, I don't work. Other than exercise, I have a lot of free time, so I spend enough time online to read. People'd be surprised the information available on line for you to search, not just politics, science, engineering and all. I am still designing very high end hifi amps, I get information on line, reading other designs and all. Internet is the most important thing. As soon as you mention the name MagnaMax, took me 2 minutes to find the info.
Have a nice day,

Every real man should know how to sharpen a knife effectively; Whetstones, diamond stones, work sharp type contraptions etc they should all be in one’s repertoire plus how to strop effectively with diamond paste.

It's very easy. Not expensive to buy all the stones. I even have a belt sander to reform the edges. I am sure they have plenty of youtube stuffs on this.
