if infi didnt exist

VTW,

I would give CPM3V a shot for a nice machete. I have been thinking about one myself. CPM3V is basically A2 with more impact resistance and vanadium for better edge retention.

I have a 1/8" Camp knife made of CPM3V (Avatar Knife) that has held up to full power 2X4 chopping with no problems.
 
A8, A2, S7 would be my pics for big knives in that order. I don't have much faith in cpm unfortunately. Maybe someday I'll come around.
 
To be honest with ya all, i still have no clue what INFI actually is. I mean...its is Busse invented super steel, but I really have no clear idea how it compare with other steel type. I just know, it is indestructable, tougher than other....knowing tech data of heat treat and all other just gonna confused more, do me no good any way.

Then....why buy INFI, you idiot..:eek:

To me its all about the blade physically design. Busse felt good in hand. Even they were made with 440C with the same Busse design, I'll still buy it. :thumbup:

What specific HT are you talking about VTW??? On a large machete you would probably want something differentially HTed and for that I would go 5160, with a Bill Siegle HT :). Otherwise for any situation where a thorough HT steel is needed, A2 all the way. The stuff has good ductility and great edge retention. I like CPM3V on paper, but I have no real life experience to relate to.
 
A2.

Honestly, I've been perfectly happy with SR101 (52100) on the Rat users. I find them the easiest to sharpen of the three camps. D2 on the small Rats works wonders too.
 
I have a thing for forged 52100, and this is what I'd like to have from Busse if INFI didn't exist.
 
any of the steels that are used by swamp rat are excellent choices given their heat treatments - but you have to recognize that they are used partially for cost effectiveness. it was part of the goal of swamp rat to make a knife that was similar quality to busse combat, but with a lower price, essentially giving busse competition (albiet a kind of psuedo in house competition)

They make the best of what they have, while factoring in cost.

infi is expensive, but its the best. if busse combat did not have infi, I believe that jerry would use whatever was best, not what was most cost effective.


in the beginning production days it was a2. I'm not sure if jerry's opinion on the best steel has changed since then, having gotten to see 52100, s7, and d2 get used in hard use knives under his company and the in house heat treatment for strength and durability. it would be interesting to hear from him directly what he considers to be the best combination of qualities.


I don't think that a large machete always benefits from being differentially hardened. it only benefits from it if the steel being used to make the knife requires it. infi does not require that.



so what would I like to see used in a non infi busse blade besides infi or modified infi? whatever is the least likely to chip, and can at the same time be high hardness and require a great deal of pressure to bend (while taking a set before breaking). hard qualities to come by in combination. I think that s7 probably has the greatest chance of meeting all of those things, unless a world class heat treatment could be applied to a2 or a8 or any other steel to GAURANTEE those qualities in it, in every knife.

for smaller "pure slicing" blades, m2 or something with great wear resistance. THIN. as thin as possible. even 1095 at 63rc. just something thats crazy good at slicing with a thin edge.

Don't EVEN ask that question!!!! Tool steel or a CPM. Which one, BOSS?

hehehe... I went looking for jerries comment on cpm and found it, but it didn't answer the question I had wich was "has jerry commented on wether cpm is better then tool/smelted steels?". here was the comment he made:

"Matti S.,

Good question! We have explored this very question. Powdered metallurgy can offer some very strong benefits in certain ares of knife performance. However, it is not possible to take the same analysis from a smelted steel and transfer it to a powdered construct and achieve an improvement. Carbide dispersion is very good and can therefore greatly affect the amounts of carbide formers that are included in the mix. If we wanted to achieve the same level of performance as INFI in some areas, the analysis of the PM would look nothing like that of INFI.

Thanks,

Jerry"

that doesn't actually say that cpm is better then smelted steels, only that info would not benefit from being powdered. or at the very least - that certain key elements of infi's performance would either not be enhanced, or be lost from the process, to an extent that it would not be worth it.

I think. honestly reading over the statement several times all I can conclusively say about it is that jerry said that smelted infi and cpm infi would be different from each other :rolleyes::rolleyes::rolleyes::rolleyes::rolleyes::rolleyes:
