Always Experimenting With INFI . . . .

Progress is essential.

So now I have a lcabs with inferior infi, who would have thought...
 
Awesome news... Looking forward to it.

I'd really love to have my Sar 6 special edition in this "Laser Infi" I love that blade the way it already is, but I think that a better cutting ability would be the best for that blade since I don't see that as a knife to abuse.

not inferior, different. If your LCABS gets dropped off the side of rock face and lands edge/tip first into a piece of granite, you might praise the mashing ability of the softer INFI, where with the newer harder INFI it may have lost it's tip entirely. Though I don't know the limit's of the newer heat treat, I'm sure it will still be tough enough to have Busse's standard warranty on it.

Softer INFI is also likely easier to sharpen, so if you want something that can be brought back to a keen edge quickly in the field, a slightly softer INFI may serve you well.

We know that INFI can be taken to Rc 60 - 62. The wording here suggests that the current process is not able to deliver a higher value on a regular basis. I wonder what Jerry is aiming for, maybe Rc 62 - 64?

There was never a 65 RC mistress. INFI just won't go that high. 60-62 is about max. :thumbup:

Hope that helps,

Jerry :D

The average hardness of INFI in the blades produced now is 58rc, chances are he's aiming for the BAD hardness of 60-62rc. But you never know :confused:

IIRC the original Mistress and other early INFI knives were around 59-61. My guess is around RC61-63 for the new process.

IIRC, the early SHBM were in the range of 60 -62, and the BADs are there, as well; so Jerry knows how to get that hardness right now. My read is that he is aiming for something higher than has been sold heretofore.
 
I want to see 63-65 rc :eek: If INFI could be that hard and still be as chip resistant, it would be amazing IMO.

you can have higher toughness than other steels at comparable hardness. Even though it may be able to be chipped and take damage under lighter loads than standard INFI, it may still be considerably better than it's competition while being chip resistant enough to not pose a noticeable problem for general use.

LVC pretty much summed up what I was getting at. Will it be as good as standard INFI in the toughness department? No, but maybe it can be tougher than other steels at extreme hardness. :thumbup:

We have been experimenting with a new heat treating procedure for INFI that we have termed CNQ which promises to deliver a consistently higher hardness as well as, what we hope will be, a considerable increase in cutting performance on certain materials.

Of course, the incredible toughness that INFI brings to the table will be decreased, but we recognize that there are some applications where exceptional toughness is not a top priority. . . .

We will keep you updated . . .

Back to drinking. . . .

On the contrary, I am glad if you abandoned the idea of a new heat treatment and left INFI 58-60. Because INFI = indestructible, it is the company name and reputation. I don't even know what to do with a knife with more than 60 hardness units. And I bought the Busse knives precisely because of the reputation of the most durable knives in the world.
 
I tried to find information and read all the topics. It seems that they did not do this, because even small and thin knives still have 58-60. But I could be wrong, only Jerry could tell the truth.
I think I will buy small files that are designed to check how many HRC a knife has and check my two Busses with them. At least I can understand there more or less than 60 HRC. These testers have a gradation of 40,45,50,55,60,65 HRC.
