5160

I have a few blades in each steel and like its already been stated the corrosion resistance is the main difference.

A custom knife maker told me that 5160 would be great for a chopper/survival knife because it can take a beating and be easily sharpened. This has also been my experience. I find it easier to sharpen than sr101 but sr101 holds an edge a little longer.

Whoa, its like those "interesting" sisters from college. :D sensory overload.
 
The Magic to INFI at the right heat treats is a combination of Malleability and Flexibility combined with Wear Resistance.

In Soft Clean Materials the others do not come anywhere close to edge holding as established in 1999, 2000, or 2001.
Look at the Tests, in the late 90's with a Symmetrical Grind more than 1,700 push cuts through one inch hemp and would still Shave, none of the others will break 300, yet the So Called Modified INFI with the Asymmetrical Grind beat the original, and the last BM-E test went around 3,000 with an Asymmetrical Grind, and they Ran out of Rope.

Try it for your self, the difference is readily apparent, Compare the older knives with the New if you like.

But, if you Compare old INFI with New Non-INFI you will have no doubts as to Where INFI stacks up, it is not close, it is not nearly, it is Better 10 times at Holding an edge in Soft Clean Materials.

As to where the Flexibility comes into play?

Not in Whole knife Flex Tests, in Edge Flexibility.

That is in the ability to Strop the old INFI edge back to sharp after extended use, the Burr edge rather than falling off just needs straightened back out.

The Malleability? the Resistance to chipping and being able to Crush an edge back into place after Malformation? Old INFI is Famous for this, Go Ahead Attempt it with the other Three Steels Listed here.
 
The Strengths of the other Steels is Blade Flexibility and edge retention in Hard Materials such as Chopping Mild Steel and Cinder Blocks, it makes a better chisel against Hard Materials and is a Direct answer to some knife makers that liked to chop Chair legs at Shows 12 years ago.

I have done this quite a few times with, returned khukuri that were abused.
 
That is where 5160 shines so bright, in a differentially hardened khuk. I dont know how many times I've been able to simply steel a big dent out of the edge. I have yet to chip it, even when chopping roots out of our rocky ground for a slightly nervous cable guy to install new cable a few years ago. :)

He asked for a hatchet, I said I had something much better. :D

My ASM B9 edge is the main reason I use this knife over my DFLE and my Camp Tramp ... but also my SAR8 with a fully convexed edge ... nothing I have in Infi / SR77 / SR101 last's as long as the ASM edges on my M-Infi ... except my B11 ASM Infi ... and these two seem to me to be the same ... both last longer than my convex edges ...

One day I will order a Nuclear Zilla with an ASM edge ... never understand why these are not brought back as a regular option ???
 
Abused in what way?

You should see what people do to their HI knives to take advantage of a no questions asked warranty, oh yea! Wait, didnt a fellow shove a Skeleton Key into a cinder block and kick it? Yea, that kind of thing. :p :D :eek:

That warranty went the way of the dodo....... Now you void your warranty if you chop wood with anything thinner than 3/8ths .......BUT that is a conversation for another Thread/Forum/Time

He HAMMERED it into the concrete, then could not pull it back out. So he tried to kick it loose.
 
Someone far more Knowledgeable than my self on the subject once described 52100 (SR101) as '5160 with attitude'.....I think that was a great description !

Times do change, sometimes better, sometimes worse. Sorry to hear about that.

thats right! I had forgotten how he got the darn thing in there, amazing how it even survived the hammering. My SK has such a fine point I'd be nervous about hammering it into wood. Its a slicer, not a tent spike. :p That thread did cause quite a stir didnt it?
 
As to "deep" corrosion, IIRC 5160 is used for vehicle leaf springs. Consider the conditions they are exposed to and why it is selected for those conditions. Ever see an old leaf spring? Pitting?
 
Leaf springs are very well coated against the elements ... more so than a knife ... which ideally for food prep needs to be uncoated ... and uncoated Infi is more corrosion resistant than 5160 from my use of both ... that being said ... 5160 or SR101 if looked after properly has not corrosion issues for me in the majority of use that I do which would inhibit it's use in an "all round knife" ...

The issues I notice are the design of the knife ... it's edge geometry and suitability to given tasks ... the Heat Treatment and edge lasting capability ... I would place these as being more relevant to "choice" than the type of steel if the steel is one of those mentioned in this thread so far ... because they can all work well ...

If I could choose the steel for the given knife I want though ... I would choose Infi ... mainly for the advantages in toughness and malleability ... it can stand more abuse than anything I have seen todate ... and equals other steels on holding a good edge and is very corrosion resistant ... on these issues it eclipses 5160 ...
 
PeterPHWS, I have to disagree with the edge holding being even, or even on par with even there own SR101, what better blades to compare would be the S5 models, INFI vs 101, same everything else, ( couldn't ask for anything closer to compare) I did 5 of each.... from stock sharpness to getting sharpened the same, and 101 pretty much walked away from INFI, except corrosion,---left out for a few days and 101 showed rust where INFI didn't, holding an edge though? INFI is a simple 5 out of 10 star rating in my opinion.

Damaged thru improper usage and care.
Believe it or not, even INFI needs proper usage and care. As long as someone isnt going all Noss4 on his khukuri, Auntie will usually take care of the situation. The onus was put upon the end user to use his blade responsibly, and rightfully so. I suppose we could afford to have a "no questions asked" warranty if we were charging $600 a blade. I believe we've already had this conversation......

I do believe that Bill Siegles assessment is spot on.
 
Tape off two inches of Blade, Push cut through Clean Dry one inch Hemp Rope sitting in a trough made of Pine.

Using a Factory Shaving edge with each knife.

INFI at least in the old Knives will just get sharper the first 300 cuts, about the time the other Steels will be lots to Dull to shave with.

Cutting Sod? The SR101 just plain Shines, Great Stuff leaves INFI in the Dust so to speak.

Cutting Clean Pine, once again the INFI edge will tend to out last the SR101 many times and is much easier to resharpen.

I did my Tests Back when SR101 was the New thing.

If, in clean soft Materials the INFI is not outlasting the others, Call the Factory and ask questions because Some thing is very Wrong.
 
I imagine the $600 price tag reflects what goes into the knife....material, equipment, labor....etc. So I think the $600 has no bearing on the warranty, as it was the same warranty they have had when their knives were less than half that...........

I dont think I've ever spent 600 on a Busse knife, well maybe a sword, but not a knife. Most have been in the range of 200 to 400.

But I dont have fancy tastes, I do prefer plain no nonsense finishes and handles.

I have handled and worked with knives that blow that 600 out of the water, and not by Busse, and not much more advanced techniques than the Kami's.

A maker commands what his experience and skill ask for, weather it be a highly advanced CNC wonder or a hand forged hand ground piece of art.

Maybe its time to sit back and not think about what the other guy is buying and criticizing it, but respect his choices. I wont spend what some of these guys are, but I wont look down on them for it, and I wont look down on the fellow that wont spend 150.00 or even 50.
