IS CPM 15V BRITTLE?!

- This is a Special Heat Treated I did in my shop after lots of research and testing.
The Hardness testing was done third party by Lisin Metallurgical Services.
Geometry is everything at the edge of the day.
Durability and Cutting Ability are an inverse relationship. No free lunch. I can make the knife the same Geometry as most production pocket knives and still pound 16d nails. Yet why leave so much Performance on the table? Just go thinner and don't use like a dummy. Thin Geometry is what cuts and with that kind of cutting Geometry with this kind of Stability on a knife this hard with this much carbide it should cut like a boss.

This is an awesome demonstration of how with the right geometry you can really stretch the capabilities of a steel.
bingo
I need me a BBB fixed blade! Hopefully I get a chance to pick one up.
Your killing it brother.
Great work man!! So impressed of your knowledge and practise!
Damn! That's the steel going into the Spyderco Manix sprint run? Gonna have to get one.
Dang! That is some impressive stuff.
Nice video! Looks like a winner. : )
Proud owner of a BBB mule team 15v.
Redonkulous!!! Nothing more needs be said brother, only cheers....
Very good demonstration.
Thanks Mick
Buddy between you and Mike Christy, you fellers have set the bar high in the knife world!! I would like to pick your brain on a hang up I am having with honing straight razors.
I may venture into super steel with knifes one day, maybe start with S30v, right now I am just a one knife man, it ain't much, but it is to me! Just a regular ole casexx!
Good info you have on this channel!
Hard work definitely paying off you are doing some amazing shit hard work dedication it really shows you have came along way very fast keep up the good work impressive
Thanks brother
BADASS BROTHA!!!!!👊
yep.. :-) just gives 'ya goosebumps !
Isn't it bRiTtLe?! You better tEmPeR that!! 🤣😜
Hahaha love it
Holy Admantium Batman! One of Wolverine's claws!
Lmao dead, I'd rather go thinner. Good stuff though
How thin behind the edge you think is practical for intended use? .010?
@@joshuabriggs7114 depends on who is behind the wheel of the car. I'd say yes, but ya never know with some folka
@@FearNoSteel Ain't that the truth!
You ever watch something and say holly shit out loud because it just happened to me awesome video Shawn(Triple B)
Phucking Lovin It B!!!
Sweet 👍
I'm awaiting delivery of my Spyderco Manix 2 with the 15v right now. The mail moves too damn slow. I'm breathlessly eager to try out the steel you helped to improve.
You see, this is why I spent just over 400.00 for the 15v Shaman ...and probably will also get the 15v Manix-2 .
I was promised flying cars in 2000. This sorta makes up for it.
Godamn!!
Nicely done. What are the weaknesses of this heat treat?
None? I think you mean weaknesses of the steel itself, it's difficult to grind when this hard. Can be difficult to sharpen without gear and techniques and it won't pry bar or make a good axe.
Big Brown Bear yes I mean that obvieusly.
I would assume this to be very weak in lateral strength wieh no flexibility.
@@8thsinner nah it will still flex
You should post this video on M390 thread 😉
Too many heads would explode. "Reeeeeeeee" hahaha
Properly heatreated M390 can indeed cut nails in half.. dont shit on that steel just because companies dont HT it well, they would do even worse with 15V.
@@micgalovic The reference was to a specific thread on BF where a member was trolling against higher HRC M390 mistook BBB for someone who keeps most his knives as safe queens. It seems I may have to post this video there because the guy has gone complete bonkers.
I'm sure it could, I think what I've learned is that the limit seems to be 0.020 bte and 20dps for most steels with good HT. There are a few steels able to go down to 0.015" and 18dps but are not as wear resistance or corrosion resistant. However, I predict with this same testthat m390 would be more likely to chip. High Chromium combined with High carbon is detrimental to stability.
Between 3v and 15v which is tougher and which stays sharper for longtime?
3v is significantly more tough, like by a lot.
15v has infinitely higher edge retention and wear resistance.
They are like the polar opposites of each other, with that being said I am not discounting edge retention of 3v, or toughness of 15v I'm just pointing out key difference between them.
Would you say 4v is more or less in the middle? How much less tough is 4v compared to 3v?
0.02"mm bte, angle of sharpening 20° per side🙂 what could happen with 0.01" bte and angle 15° per side😉 the key is "know how" to prepare geometry for such a test😊
Again, if you want that question answered, you need to send me the knife, and I'll find your answer!
Hahaha love it
Hey BBB, have you started making taking any order for Gyutos?
I got a 10v gyuto I need to grind
You need to pat yourself on the back for your work man.
Eyyyy if this blade did it at 67HRC then the manix2 should have zero problems at 65-66 no? 🤔🤷♂️
Could be, there's a difference in Geometry though.
Take a page out of judge dredd and yell out "I AM THE LAWW!!!" when foolish questions or statements come up about brittleness or durability. How did the heat treat hold up at specific geometry on the rod of truth is more valid sets of questions.
Amen
What would you compare the toughness of 15v to? I am getting so many different answers and I don't trust any of those soup heads telling me this stuff. I need the all father himself to spell it out plain and simple.
bad second paper test, but I believe it's OK
Yes, it is. Is it brittle enough to fail doing what you just did, no.
Might just be durable enough for a knife, just maybe.
Ahh man hurts to watch
