S30V? Really? – For the steel junky.

I have do the same abuse with a $10 mora 510 carbon steel & the Mora is like NEW no damage occured.
I think S30V is Brittle & i will never buy an S30V blade again!
 
what i done is not so important,the result is the most important.the Mora 510 is in perfect shape & the alaskan guide is DEAD.
 
some people will think (what about the edge holding?) well my $10 Mora is very good in this too.
 
Olaff your photo serves no purpose in this thread if you do not tell us how it occurred and under what conditions. I can take my carbon Mora and shatter it as well, but it could be from using it in extremely cold conditions to baton wood or I could just take a sledge hammer to it. What exactly are you intending to prove to us by posting a picture of a broken knife with no words describing the breakage, especially from a well regarded manufacturer like Buck that typically has superb heat treats?

I have videos of my pounding S30V blades through PC power cables and doing light chopping and batoning, on a knife with an edge much thinner than your Buck. If you tell me how you broke your Buck and the task you were performing is fairly rational, I will be more than happy to duplicate it ith one of my Spydercos in S30V or if it's capable my S30V buck Hartsook.
 
Take two similar knives in size and thickness and abuse them in same way. you will see the stronger steel. S30V is fragile.

maybe a super steel for much knife uses but fragile.

I forced a door,i know its not a knife task.
my goal was to break the knife.
I done the same with a Mora Carbon Steel,and like a said the knife is in perfect shape.

everyone is free to choose what he want in a knife.
I dont want a fragile,brittle steel.
MY CHOICE
 
Did S30V ever prove too brittle for cutting tasks for you? Do you typically breech doors with your knives?

Me, or anyone else I'm aware of, do not advocate S30V as a high toughness steel. It's praised highly because for the things that the average person typically uses their knife for, it works well. If someone needs a tough steel there are better choices, but as a general utility EDC S30V is a good choice.

I was under the impression that for a given steel there is a trade off in toughness and hardness. The fact that a 5.5" or greater combat/survival knife has a lower hardness then a much smaller and thinner folder just seems to make sense.

Also, isn't hardness also an indication of edge retention within the same steel? Yes, I know there are other factors but the same blade with a higher hardness will generally have greater edge retention as long as it isn't too hard and you get any sort of shattering on the edge even microscopically.

My understanding is that you want a blade's edge to be as hard as it can be AFTER a knifes toughness level is already determined. A s30v blade, or any other steel for that matter, can be made to be much much tougher if it is left at Rc40 then tempered to Rc60. The Rc 40 edge can have an awesomely sharp initial edge but squat for edge retention. I'm sure that an s30v blade or edge can be hardened to Rc65 but it will then have crap for toughness and probably be extremely brittle. A different steel, like zdp-189, might be tough enough at Rc65 to be fully functional in a smaller knife, like a folder, and still maintain killer edge retention.

Before sending the knife out for re'heat-treating why not contact CR and discuss with customer service what happened. If cutting a wire or two voids their warranty then the company isn't worth your money. They might take the blade back for testing, who knows, they might have had an issue with that batches heat treat. Let them fix it before paying more on an already pricey knife to have it done by someone else.
 
Hey guys

If you use a knife it gets dull thats the way it goes there is no super steel.

If you use you car your gas tank goes empty. No way around it. There is no infinite MPG car

You used a Buck 110 to try and pry a door?

Okay....you know you could have used the Buck to just cut around the handle and lock....:rolleyes:

No, what you did with the blade is very important. S30V was designed to hold an edge for a long time, and will be relatively brittle compared to a much softer steel like whatever is on the Mora 510.

So you set out to break a knife, and now that you've successfully broken the knife, you came back on here to tell us all how much it sucks because it broke.

...Cliff? Cliff, is that you?

Dont take this as a flame, but you're joking right? The Sharpmaker can make a butter knife into a razor in 30 minutes.

S30V is the real deal. Dunno about CR knives, I dont spend that much (limited run, excessive hype, bonkers price, blah blah, overpriced...Busse syndrome), but the Kershaws, Spydercos, Benchmades, and Bucks in S30V are rock stars. The only steels on that level of overall all quality, imho, are VG10 (more brittle, i shaved metal burs off conduit before chipping the edge on my Native), A2 and D2.

I still love CM154. If you want the most wicked cutting edge ever, get one. It isnt as resilient, but it can and will cut like no other steel. Holy sharpness Batman!

You failed to mention that you think S30V is brittle because you broke an S30V blade prying a door open. A door which you never intended to simply pry open, but where you stated your aim was to break the knife.

And then you accuse me of trolling for calling you on it, and throw in a jerkit smiley. Something 'wrong here.

I agree and those little widgy prybars are great and they make short work of painted shut cabintes and windows.


Not to mention they do a decent job of opening boxes and packages too.
