Another Newbie Question: Busse Knives Cryogenically Treated?

resinguy said:
How would you have cryo treated your own knives?

Why would you? Is is necessarily the best process for all steels? If you don't know the metallurgy of INFI, or anything else about the complete Busse Heat Treat cycle, what leads you to think that you could improve on it?

I'm not trying to bust your chops, just trying to understand your thinking. Thanks.

i don't know of any steel that doesn't get any benefit from it, but, generally speaking, higher carbon content steels get more benefit.

SteelNut, are you pulling my leg or is this an actual metal treatment? I am interested to know more.

"Transversion Wave" was/is the heat treatment (specifcally tempering) for the SR101 steel in the Swamp Rat line.

Taken from here: http://web.archive.org/web/20020607011344/www.swampratknifeworks.com/specs.html

Heat Treat and Tempering

It is in this process that the very soul of a blades performance will be born. It can also be the most expensive process involved in the making of a fine blade. Sadly, the knife buying public has been led to believe that Rockwell Hardness is some sort of gauge by which to determine performance. This is ridiculous! Following standard ASTM heat treating and tempering protocols, a blade made from a standard tool steel can be "properly" heat treated and tempered in less than 1-1/2 hours and brought to a hardness of 60 Rc. So what! Take one of our blades that has received our proprietary heat treat and tempering protocol of over 40 hrs. and it will also test out at 60 Rc. The fact is that one of our transversion wave tempered SR-101 blades that tests out at 60 Rc will spank the living hell out of a standard heat treated knife blade out of the same material that also has a 60 Rc hardness.

Grain structure, direction, and carbide distribution, are the keys to great performance NOT Rockwell hardness!

I don't believe that terminology was ever applied to the INFI line. Maybe Jerry will tell us.

Welcome to the madness my friend. . . We heat it, we freeze it, we drink it, we eat it. . . good times. . . good times!!!!

Ah, You just hang there to be with UJ:p

I'm kidding, I'm kidding Dwayne!!!....and UJ

I did just go there for the first time in months and it was still pretty dead though. Was only 75 people on the whole site. Only 3 in the production knife room, and about 5 in the custom knife room. May just be to early for Devils though???
 
I'm actually curious why people think JD is a cool forum. I've never hung out there, so don't know anything about it. What's it like?

Your not missing much IMHO, but I would go check it out just to see. You may like it.

Some here do go there, so there must be something appealing about it...just havn't figured it out yet.
 
Wasn't Ted Williams Cryogenically Treated? He was already a pretty tough dude; do you think it made him tougher?

We do a dry, multi cycle, deep cryo treatment. :thumbup:

Jerry, have you gotten anyone yet to do manicures and pedicures? I'm looking for the complete spa treatment, and Busse is on the short list now.
 
I knew there MUST be a reason I kept my infi in the freezer....just so happens to be next to my vodka.
 
Of course Busse blades are cryogenically treated, that is why they are so.........






























COOL!:cool:

Guyon---You'll get your answer in the; Scissors, etc. Forum. :p

Touché. :D Actually, I'm trolling that forum next. Now that I have my trolling card, those guys in Razor and Scissors better be on the lookout. :p
 
Actually the heat treatment only involves 2 hrs. of treatment but with Jerry in there with a bottle of booze it just TAKES 80 hrs to complete!!!

I would be surprised if INFI steel is cryogenically treated to -300F thats a long and expensive process to do I believe.

yes and no. it does add to the overall cost of production, but cryo treatment of a blade on the secondary market is equal to that of heat treating, anywhere from 5-25$ per knife. all it really involves i putting a knife into a chamber thats heat regulated by a cooling agent and running the temperature down, hold, then up x amount of times. if the equipment is already there, your not incurring a great deal of materials or manpower costs, it's more the initial set up that kills you capital wise.

it could be benefitial on a knife thats been beaten to all hell for several years. when you've compacted the metal at the edge over and over and over again, pried it back and forth x amount of times, and thrown it at logs for hours on end, you can have built up stress on the metal that can be releived through cryo.

i think? :confused:
 
I wonder if the 2 hour heat treat is on the same time warp as the Busse family 2 weeks...
 
I'm still as amazed by INFI as I was the first day I got my FFBM in the mail. I just finished clearing a large tree that fell on a path on the farm, chopping for at least 2 hours.
The amazing thing is that the blade was still sharp after.

I need to get more of that stuff.
 
Yeah , me too. I am comparing my Busse to ATS34 and a Randall SS knife and the Busse holds an edge much better than either of them. It's interesting to know that Busse does a Cyrogenic treat. It is a great steel and no doubt due in part to the tempering process.
