Why does CPM-M4 dominate in national cutting competitions?

"How does INFI compare to other steels?
Unparalleled edge holding under high impact and in cutting tests. "

This is from your website Jerry.
Is it true or not?
The Bladesports contests would either prove or disprove this.

M4 shows unparalleled edge holding under high impact and in cutting tests.

Yowza!!!. . . You're gettin' kinda worked up there little fella..

As for "Excuses", what do you call the resounding silence of those who haven't taken our "LIVE" challenge for the past 11 years? :confused:

In regards to my statements about INFI being "true or not?" Our "LIVE" tests and demonstrations with INFI have proven this to be true. Until someone steps up and duplicates our tests and surpasses us on all levels with a different steel, INFI will remain unparalleled. Using a different set of tests that rely heavily upon the expertise of the person doing the demonstration would prove nothing in regards to the abilities of the steel being tested.

"M4 shows unparalleled edge holding under high impact and in cutting tests." - Bearcut. . . . . Really?. . . Well, that sounds exciting! :eek:

Feel free to call up the manufacturer of CPM-M4 and tell them that you want to be the official representative for their company at BLADE 2010 and that you are going to duplicate all of the tests that Busse Combat has done previously with INFI in a "LIVE" demonstration! ! ! . . . . I'm sure that they will be very excited to have you on their team!. . . You go get 'em tiger. . . . I'll stand by while you get the official "Okay, let's do it!" . . . :thumbup:

PS. If you would like to discuss your deep seated need to troll against Busse Combat, I am available at (419) 923-6471. :thumbup:

Well it may be turned around this way - are there any prove that other steel can not doe this, did you try any other steel, or did anyone ever?

It was one man race no wonder only one who participated this won, but when I did similar rope catting measuring edge sharpness during cutting for 27 steels INFI results was not really on the top. And of course I did not do this to extreme thousands cuts but it is easy to extrapolate.

Now Taledo from guns.ru did rope cutting way more then me over 2100 with more or less average steel knives here:

Number of cuts is more or less show will to cut by tester not to much about knife property - key here is how sharp it stays during this exercise.

Here Roackstead ZDP knife - over 780 cuts too and very sharp at the end:

I am sure, based on my rope cutting experience, average steel can cut rope many thousands times, until you damage your wrist. This is what finally happened to me after way over 5000 cuts I did total.

Thanks, Vassili.

Is the number (419) 923-6471 ??? :D :thumbup:


Why must every thread about any kind of steel result in Vassili countering any and all claims with his rope tests, and lowlifes coming out to bash INFI?

I swear I could start a thread about 440c vs Aus8 and after 10 pages, it will still revert to cutting manilla rope and INFI bashing :thumbdn: :barf:


Can we PLEEEEASE get back to the competition discussion? It was quite interesting. :grumpy:
 
Donavon,
Welcome, you're an animal - nice cuttin' there.

You mentioned that the stainless steels haven't held up - did this apply to 3V? Also, can you comment if D2 fell in that category too, or has it held up?

Do you guys retire an M4 blade after a while?
 
:rolleyes:I believe they do, Broos. I saw one change hands after the recent Blade 09 cutting competition. And heard that another one was changing hands.

I've only seen one of these competitions ... but I was quite impressed. A whole variety of different cutting tasks, one right after the other. Some need a strong, wide swing and some need a gentle, precise cut. The crowd really got "into" it, which probably made the cutters' task much more difficult (try being careful and precise when you've got a load of adrenalin in your system).

Oh. Bits and pieces of objects (rope, straws, wood) were flying literally everywhere. I was a good 40 feet away, and I caught a piece!!:)

The narration was ... sparkling!:eek:
 
Donavon that was some awesome cutting :D Holy crap, at one point it looked like the 2X4 just exploded :eek:

I have a question. It's been mentioned that if a blade edge suffers too much degradation after the cutting tasks it will be disqualified. Can you give us an idea of how much is too much.

Thanks for your informative post :thumbup:
 
At the Blade Show Donavan went through the first 2x4 in 6 swings. If you listen real closely you can hear the boards beg for mercy when Big D walks up.

I like the pursuit of excellence in sport and in knives....and the competition cutting sport gives a great oppertunity to combine this...however if I bought a Jeep or Landrover as a general workhorse vehicle....I would'nt expect it to match up to a Paris-Dakar type racer...it's horses for courses as far as I can see in terms of comparing Infi and CPM M4 ....the later has been used with a specific recipe in mind in competition use where for example rolling a blade may disqualify the cutter...whereas Infi is a steel designed to roll and not chip if being used to chop through mediums like concrete as seen in the breeze block tests...on the basis it is a benefit to simply strop it straight useing a sharpening steel rather than re-profiling the edge to remove the chip....but with the intended use of CPM M4 the roll is not desired so it is hardened higher on a Rc scale to prevent this but if used on concrete it will in all probability chip and fail.

My point being that each is good in it's own right at what it was intended to be good at.....as to whether one is better than the other....to me it is not quite "apples to apples"....although if Infi were to be given a bespoke heat treatment to enable it to maximise it's "competiton" possibilities I think with the right experienced cutter it could do well....although I suspect ultimately these two steels would eventually plateau out according to the chemical make up of the steel...and one would be better at certain things than the other....although which is the best steel depends on what you want it to do....or so it seems to me.

After seeing that, I could see some folks wanting one. I don't think it is an unreasonable question to ask that if some of the higher carbide steels fail (apparently via fatigue from flexing), is there concern by the competitors that a steel with slightly lower carbide fraction would experience the same fatigue, just at a slower rate. For a user and a keeper, I like cutting performance, but not at the cost of any risk of a reduced life due to fatigue from flexing. So maybe getting one a little thicker than the "competition grind" is appropriate for one you want to use for a long time, no?
 
When designing for purpose the other attributes become secondary. The more you design and prepare for one purpose the other attributes are discounted.

You don't go shopping with a F1 racer but they are great to watch and alot of work goes into them and the R&D gets loads of effort and return. For me my needs are different.
 
What specific purpose would a competition knife be made for? Chopping? Cutting rope, paper, water bottles, tennis balls, drinking straws? What about the surprise cuts where the cutters don't know what they will be until the competition?

It seems to me that the competitions are designed to test all aspects of cutting instead of a specific purpose.
 
Corrosion resistance, food prep, ease of sharpening.

I don't use a dagger or a chopper to do the onions, fruit, possible but easier with a simple stainless, mora.

Can we improve the simpler, cheaper knives from the chopping competitions - most definitely.

Exactly.

This competition tests the all around ability of a knife, which is what I look for in a blade.
This contest should be a walk in the park for some knifemakers, if their claims are true.

Mike, do you recall what steels have placed in the last couple of years?
What steels have been entered?

I have tossed the knife mags that had those articles about the competition. They were very interesting, as I recall.
