Work hardenability?

Does HI have it in their blades? If they do, I am totally holding out for one. If not, I will probably still hold out for an HI product, although I am sorely tempted by the Spyderco Rock Salt, which features work hardenability.
 
Work hardening is identical to Cold working steels. Spyderco's H1 is one of the steels that do this.

Be advised that a very small percentage of cutlery steels are this way because makers heat treat them with a furnace instead of grinding a large margin to get to a high hardness.

I think you're mistaken by how Work harden is, it's not some miracle steel that sharpens itself while you use it, you must reduce stock a lot to get the hardness of the particular area to harden
 
Thanks for the correction. I saw work hardenability and was so excited, I thought it would be like having a 'smart' knife that gets better as you use it. I should have known that would not be the case, but mistakes are what we live for, eh? Thanks again, and see you all again.
 
well its all perspective if you chop a lot with your HI -- AK -- the more work you do with that blade the muscles in your arm will get harder = work hardened ability

yeah...hehe :thumbup: :D
 
Ha ha, you guys are too much for me. Yeah, so I am over the work hardenability thing. The way I am going, I will never be able to save up for a kukri, so I am holding out for an eod breacher bar for now. Is that any good? Better yet, is it legal to carry around a breacher bar? Because I want something legal to carry that can pry like heck.
 
I would NOT carry a breacher bar.

A cop will likely see that in the same vein as carrying a set of bolt cutters -- intent to break and enter.

You really need to check your local laws. I doubt it's legal to carry much more than a pocket knife in Newark.
 
Okay, cool. Don't want to be arrested, ever. I will commit suicide in front of however many witnesses if a cop pulls out a pair of handcuffs and starts with the miranda rights on me. They'll never take me alive. Anyway, I'll ask my karate instructor, he seems to be very knowledgeable about the law, and I can't find it online, so...yeah. Never going to jail alive! Yay!
 
that wont work - it is illegal to kill yourself --- so they would have to arrest you --
--- plus add another charge to your case:eek:

I believe you can't be charged for committing suicide. It is illegal though to attempt to commit suicide.
If you suceed no problem, if you fail then they charge you.
Government logic.
 
yes - sure - that was what i meant - i mean it would be hard to file a charge on you if you were to succeed :D

It might not be so bad. You could get out and go on to become a billionaire.
(Not kidding... just google "bill gates mugshot"):)
 
I believe it. People with Autism spectrum do crazy things, and I believe I read somewhere that Bill Gates has Asperger's or something like that. I don't know exactly.... Anyway, yeah, it MIGHT not be that bad, but that was a one in a trillion chance, and I am not keeping my hopes up, nor am I getting myself arrested so I can have some Microsoft epiphany in jail, come out, and kick butt in the computer industry. Like I said, I'm totally sticking with my first statement, however radical it sounds. Jail is a place with true monsters in it, besides the fact that being stuck in a steel cell...it changes you. I would probably not even be able to live with myself if I had to go to jail, and I somehow got spat out of the system in time to live my life outside. Not to mention there's corruption and all this other stuff going on in the government and the system beneath it, its all rotten inside. No thank you, I will take death with a smile rather than becoming some haunted monster myself, I will take eternal rest over all the horrors humankind can call to mind and commit when they are condemned for life. I was in and out of MeadowWood and Rockford, in a partial and a full program, and if it was awful there, then it is worse in jail. No thank you, 'better to starve free than be a fat slave'. One more time, anyway, I checked with my karate instructor, and he thinks maybe it is legal, so I'll do some more research, maybe ask my dad, seeing as he was a criminal justice degree way back. At the very least, I'll probably get the breacher bar and keep it at home, it can't be illegal just to have it at home, can it? Maybe I should work on getting a weapons license or something like that. Whatever. I'll see all you cool people later. Peace.
 
have you thought about a breaching axe? - they can be a bit hard to find if you want an old one - the newer "tactical" are not the same they are more fore attacking or self defense - although the old ones can be used in that manner -

This one is from 1952 it was made for firefighters and was modeled after the old boarding axe's of the wooden ship days. - this is one i picked up a year ago - it is the one that resembles like a tomahawk - the other is an old goose wing from Austria made in the early 1900s
if you shop around you can get one a lot less than a hundred dollars

Those look sweet as candy, but unfortunately, I'll have to go with the breacher bar, unless I can bid on one and win it for a reasonable price, say, under 50 bucks. Not to mention my dearest mother likes the breacher bar much more than she likes mean looking axes like those. Hopefully, I'll be on my own soon enough, and have money to both help people and satisfy my cravings for knives and their ilk. I don't know...I like the portability and carryability of the breacher bar, but I have a love affair with axes of all shapes and sizes. Thanks for sharing, anyway, Eric. No wonder I don't like to post anywhere else
 
I've got a scythe blade that can be work hardened, for what it's worth. :D Of course, I still haven't gotten the hang of peening the edge.

I remember a thread from almost a year ago about work hardening. The consensus seemed to be that most knives are tempered to a degree that work hardening is no longer possible. With scythes, the steel is softer, allowing you to peen the edge razor's edge thin, and fortifying it in the process... IF done properly.
 
Cool, it does make sense, what you said about the softer steel being able to be hardened after its forging and tempering. Cool.

Here's some supporting data about the work hardening of scythe blades:

"Most makers today claim to temper their scythe blades to 45-47 Rc..."

"The average hardness in the "core" of the blade, at all three section positions, was about 430 Vickers diamond pyramid number (VHN). This corresponds to a hardness of about 44 Rockwell C."

Peening the scythe blades (hammering the edge on a special anvil) increased the measured hardness "to about 560 VHN (53 Rockwell C), in the region that had been hand hammered." [Although the hardest part of the blade, the millimeter (or so) closest to the edge, was not measured for hardness.]

Note: Peening the edge of a scythe blade is regularly done, maybe on a daily basis and sometimes in the field, to reprofile the edge after repeated resharpening with stones.

great articles - thanks for posting those i book marked em - love the old school stuff - thanks again for putting links to the source

Yeah, what Eric said, that is awesome stuff, thank you for posting. Heh, I said that like I own the forum, when I so obviously do not. Anyway, thanks for informing me and everyone else, for that matter, on the nuances of work hardenability. Cool stuff.
