What's the deal with Busse's INFI steel?

Slightly off topic, but what about the shock steels like S7... Does anybody use one of those in a folder?

Few people use them at all, in a folder the problem would be making it robust enough handle and lock wise to actually have the characteristics of the steel useful.

Keith, you are right up to a point. I think it might be the difference between American and British English. In Britain an ellipsis is often used to indicate a humourous intent. From the Greek 'elleipsis' meaning 'leave out', in this case I left out 'only joking'. Of course it wasn't all that funny in the first place and one is rather assuming that you are an American.

Actually, it's really not important. You have stated that you were only joking and that's good enough for me. No more beating a dead horse.
 
Just my opinion, but when someone is asking for information that deserves an honest answer, a joke would seem to be out of place. Maybe a smilie or two would have been more appropriate. I am glad folks jumped in with facts.
 
Hey guys... I sincerely appreciate the people who has posted a response to my ORIGINAL QUESTION (!!!!!), but to all those who have gone on arguing about "Watcha-o-homo's" name, quit slaughtering my thread please. Take your arguments elsewhere...

Regards,
Cleary
 
Although... Cliff, Walking_Man, and others like them are welcome, because they are assets to this forum, unlike some forumites who should be banned to the Bladeforums.com wilderness like the Israelites... maybe longer though.

Anyways... Walking_Man, great post on the MCHammer man... cracked me up dude... lol, :-)

FliGuy, about the butchered threads, sorry, you just have to get used to it, it happens to the best threads. And I'm glad you liked my pic. Stop on by the Busse forum for a whole lot of info, pictures, thread butchering and less bickering, you won't regret it. Glad to have you here. :thumbup:
 
Walking Man, I made a joke, albeit a poor one about INFI and Carbon V being the same. Yes I should have made it clearer I was joking. It was never my intention to annoy nice folk.
You however are not nice folk.
Ignoring each other from now on sounds like a plan.
Everyone else, sorry but I don't like being insulted.

Thanks Cliff! Maybe this is why Mr. Busse's taking his sweet time. :rolleyes:

Here we go again. :jerkit: INFI and Mod A-8 are not the same steel. Do a search and read all about it before posting erroneous info that has already been discussed in the past.

Mod A-8 as used by Johanning is a great steel in of itself (in part due to Johannings HT, I am sure).:thumbup:

I have found both chipper steel and some companies' A8 mod. that had the exact same composition as INFI (within a few tenths of a percent of course). You're the one who hasn't done any searching.

Larrin,

There are MANY steels that are within a few tenths of a percentage of another grade of steel and yet they have earned their own specific grade designation.

Looking at the composition of a steel and making statements about its edge holding and other performance characteristics is like reading a recipe and telling people how something is going to taste. . . it's pretty far out. Here's a post that you made on another forum concerning INFI.

Here was my response,

". . .average at best edge retention"???

In a "LIVE" demonstration at the BLADE Show we made 2,771 cuts through 1" diameter hemp rope with the same 2" wide section of an INFI blade. That small section of blade still easily shaved through paper. We, likewise, cut 3,132 pieces at the Nashville show and bent the same knife over 70 degrees without damage. Is this what you call "average at best edge retention" ??? If so, please direct me to ANY other manufacturer who has repeatedly done "LIVE" testing in front of the public at major knife shows or one who has come close to this level of performance and proven it in a "LIVE" public demo. . . . NONE have.

"Hype" has been defined as "Something that is deliberately misleading; a deception" This definition of "HYPE" fits your unsupported remarks far better than does the proven performance of Busse Combat blades.

We have invited every major manufacturer to step up and do "LIVE" performance testing with their own blades. . . . none have accepted. . .

After I posted my response, you then posted the following,

That's a pretty big grain of salt. . . don'tcha think?:confused:

I don't really care what the composition of a steel is. . . I only care about its proven performance. So, with that in mind, could you please direct me to ANY "live" demonstration where anybody, anywhere at any time has come close to duplicating our performance???. . .or better yet, direct me to where someone has at least had the cajones to try?

Anybody. . . .anywhere. . . .at any time?

Jerry Busse
 
DaveH,

I am familiar with the Boye test. My understanding is that it was not done "live" in front of the public. Boye, likewise, used the entire length of the blade where as we only used a 2" section. The Boye knife will, likewise take very little lateral pressure before snapping due to it being a cast steel.

The Boye knives are awesome cutters though, no doubt about it.:thumbup:

Thanks,

Jerry
 
From what I could find doing a search the carbon, chromium, molybdenum and vanadium content of INFI and A8 Modified fall within the same percentage range. A8 Modified contains manganese and silicon that are not found in INFI. INFI contains cobalt, nickel and nitrogen that are not found in A8 Modified. The fact that they have such a different chemical makeup would lead me to believe that they would not have similar characteristics.
 
A few tenths of a percent of alloy composition are pretty much all that seperate 440A, B, and C. Clearly they're the same steel and have the same properties.

Actually, there's only one type of steel, which isn't that different from iron...

I know the differences between steels, and what makes one different from another. I know no one is going to believe me, but I have seen steels sold by other companies with the same composition. Just because another company makes the same alloy doesn't mean INFI is bad, if anything it should mean it's good. Looking back on it, there may be enough difference in composition between A8 mod. and INFI to make some small differences, but I still doubt that there would be much to notice. I think if someone made a knife our of A8 mod. and another out of INFI, no one would notice any difference, but that's another subject entirely.

As to my saying INFI has average edge retention, this is of course in reference to our "super steels" of 3V and others. 3V in theory should have better edge retention because of higher carbide volume, harder carbides, and same or higher overall hardness. This doesn't mean INFI doesn't have good edge retention. 52100 has relatively low carbide volume and has great edge retention. I admit I too may be falling in to the trap of only looking at wear resistance.

I'm not trying to say that INFI is a bad steel, or even an average steel. I find it discouraging entering a thread when everything I say is attacked, and you have to defend everything from your favorite knives to your children.

By the way, here's the closest composition of A8 mod. to INFI that I could find in five minutes, if anyone's interested. Feel free to attack me about the major differences between the steel that would make them different. I find the differences especially interesting.

C 0.5
Cr 8
Fe 88.35
Mn 0.45
Mo 1.3
Si 0.95
V 0.45
 
Do you actually bother to read other threads that discuss this before osting?? Obviously not. We just had a big discussion on this and here you go. You are missing several MICROCONSTITUENTS!!! .:thumbdn:

I understand that you are not knocking INFI or any other steel. Read my post to you, maybe you can understand if you read.

Larrin, please find the COMPANY and the STEEL that is exactly like INFI in composition. Bohler k329 is not Mod A8 is not. Please, inquiring minds want to know, where is this other steel you found. :jerkit:

I don't see what the point is in finding the exact steel. I never have, nor intended to find the exact same steel. If my posts say otherwise, I'm sorry. The original question was asking what it is similar to. I said what it's similar to. You're arguing for the sake of argument. Stop it.
 
Larrin did you know that humans are all similar accept have a habit of acting differently, looking differently, and just all around are different?

same with infi steel. It mayb similar to other steels but is not other steels.
 
[52100]

This would be why your comments are getting harsh critism. Compare the work done to promote the edge retention of 52100 to the demonstrations by Busse on INFI and then explain how 52100 deserves the great label and INFI only adequate.
