INFI

what do the letters stand for?

How does it compare to cpm3v? (alright i know it is better :foot:)

When was it created?

How many tries did it take to create?

Does it throw a spark for starting campfires?

What does Nitrogen do to steel?

and who makes the steel itself?

Thanks for helping out a newbie!

When was it created? Not soon enough.:D

How many tries did it take to create? Probably only Jerry knows.

Does it throw a spark for starting campfires? I haven't tried it, but I know some have. I think most have said they just needed a sharp edge on the spine or in the choil to use their firesteels.

What does Nitrogen do to steel? ?

and who makes the steel itself? Again, probably a closely held thing.

Thanks for helping out a newbie!

I know that doesn't help much, but I don't know much anymore. :)
 
Thanks progunner, I just find it odd that a knife maker could make a steel that is better than the work of countless brilliant metallurgists who have invested their life's work trying to find "that" steel or heat treatment process. It does have nitrogen in it , right?

what do the letters stand for? Dunno.

How does it compare to cpm3v? It's more impact resistant, tougher, and holds an edge better. It's basically better. Though CPM3V is a great steel too.

When was it created? I think the first INFI knife was with the first SHBM and the SHSH/SHBA at that same time. I think, I dunno for sure. Around 1997.

How many tries did it take to create? An FINIte number of times obviously :p.

Does it throw a spark for starting campfires? Dunno, but I have a SHBM that throws fireballs!

What does Nitrogen do to steel? It makes it happy.

and who makes the steel itself? It's made of salvaged scrap metal from UFO's.

Took a swing at it :p
 
I saw a video of soldiers shooting a genuine katana with a 50 cal machine gun. on the high speed it survived 6 shots. who wants to try this with an AK? it would be neat :D
 
INFI (don't know what it means) is more then just the steel. It is the combination of the metallurgy AND the extensive heat-treat process. The steel composition itself is known, and has been posted on BF, (sorry, no link). Yes, it has nitrogen, but I have heard only speculation about where it comes from, or what it does for the steel. Some folks have speculated that the nitrogen is the result of some unique step in the process of making the steel or treating the blade.

Thems who knows ain't talking. :rolleyes:

Anyone dumb enough to spend what it would cost for a pile of .50 cal ammo.
 
This is the chemical make-up of IFNI steel as confirmed by Jerry Busse.

V .36% Vanadium
Cr 8.25% Chrome
Fe 87.79% Iron
Co .95% Cobalt
Ni .74% Nickel
Mo 1.3% Molybdenum
C .5% carbon
N .11% Nitrogen

This is what is commonly posted when searched for. I should have just done a search, In my high school it is required to give a list of goals for life. As a young knifemaker i thought of ways to further the craft with my own process. INFI is what I first thought of and i wanted to know the process of making a new product.
 
BTW INFI throws sparks off a firesteel just fine. I do it all the time.

You find it odd?

No one today can duplicate the swords made in China thousands of years ago. their hardness and flexibility was legendary, and they had none of our "modern" technology.
Where do you think the term "black art" comes from? How about the generations of alchemists doing experiments?


It is most definitely the process. I'm no metal-guy, but there an infinite number of ways to temper, and lots of different times and temperatures.

I'm a bread guy, and I can tell you that there is literally no limit to what can be done with flour, salt, yeast and water.
 
ok then i don't find it odd, but you won't see me making something that awesome, i still think A2 is a tough HT...

Well said, and who says Jerry isn't a brilliant metallurgist?

Who says he isn't? from the tiny bit I read on the forums he was a custom knifemaker, Its just the fact that I hear little on how hard it is to make ta steel like INFI and more on just "he made it."

Im seriously considering my first busse knife, I like the fusion battle mistress CG... If its a tough steel, why not get a big, high leverage knife? :D

when you see the base microconstituents of Cr and C are 8.25% and 0.5%, respectively, I think you can find a few steels that match that. So you can get pretty close. Tom Johanning uses modified A8 which has 8.25% Cr and 0.5% C. Bohler K329 also has those two same components. However, the other constituents are different and may give slightly different properties. also the HT is a biggie. I think Jerry could make any steel perform beyond it's applications and he has proven it with ATS34, D2 and A2. Not to mention modified 52100 an modified S7

It would be a great first Busse, they are currently available at essentially the original cost. It's a good time to be a buyer, not so good for sellers. I'm both. :rolleyes:

Oh thanks, but im not intending on duplicating another maker's product, but I've heard how well Jerry treats his steels :)
 
WHAT :eek: NO DUCCI :p i JUST CAN'T BELIEVE IT :D :thumbup:
