Did u do any spine whack tests and did the lock fail on the 0300? I ask because that hammer made the 0300 folder close. Thanks for the destruction tests!!

[KnifeDealsPlus]

No, I did not do any tests on the lock, I should have before the knife was broken. The 0301 did not like getting hit on the tail end with a sledge hammer, and did come unlocked a couple of times. I would do the tests different if I did it again, but once they are broken you are done. No second chances, unless you want to damage another knife. Thanks!

[KnifeDealsPlus]

Yes, the 0301 did loose its lock when I hammered it into the block of wood. I am not sure why and would have to do the test again to find out. The next question would be do other knives also loose the lock when hammered into a wood stump.

painful to watch these knifes being deliberately broken!!!

[Gungrave123]

I wouldn't call this "test". Its just intentional destruction..

[cbr600rrturbo]

is the cpm3v steel better than the s30v ? thanks

[redeemer61190]

This was quite intense thank you for these tests. Do you think the discontinued ZT 0500 MUDD could stand up to the abuse like the 0200 and 0301 endured?

[5440Borderline]

What was the point of this particular test? What task could possibly require applying that much impact force to the side of the blade?

@kimber1911fan Carbides contribute to wear resistance and are inversely proportional to corrosion resistance, all iron carbides rust. Nitrogen does not 'free up' chromium; the amount of carbon does. H-1 is ok; very tough for a stainless, but as a work hardening non martensitic steel, edge retention is meh. Also, though INFI has higher tensile strength than S7, the stock thickness of an FFBM is almost 1/3 of an inch, dumpster mutt is 3/16"........enough said.

[kimber1911fan]

@RebelWrestler45 just lol........

carbides = wear resistance not rust resistance

more nitrogen = less carbon = more free chromium = ALOT less rust as the nitrogen frees up chromium trapped in carbon so not only would it have less carbon but would have free chromium as well making it rust less, also H1 is a great blade steel and spyderco uses it alot, also look at nosses tests, a FFBM lasted longer than a dumpster mutt in S7 steel

[RebelWrestler45]

@kimber1911fan H1 is not a martensitic steel, but ALL steel will rust because all steel contains carbides. There is no such thing as a 100% corrosion resistant steel. Free chromium is simply chromium not contained in carbides; nitrogen does not 'free' chromium, lack of carbon does. INFI is simply nowhere near as tough as S7 or L6, and depending on the temper, 52100. All 3 steels also have far greater ductility. INFI is great, but it is not the end all be all; the steel must meet the application

[kimber1911fan]

@RebelWrestler45 nitrogen frees chromium making it more rust resistant, H1 uses nitrogen and it CANT rust, do you know anything about steels? 5160 is ok but infi still wins, busse uses 52100 in swamp rat knives and infi is still tougher, L6 might beat it slightly lol all tho 52100 holds an edge longer it is no where near as tough, and infi is ALOT more rust resistant than D2, its more like 154cm/ATS-34 according to salt water spray tests.and infi beats s7 is noss's tests and s7>>>5160 or 52100

[RebelWrestler45]

@kimber1911fan I think Busse sold you a bill of goods. INFI has stain resistance close to that of D2 because it uses nitrogen as a hardening agent; but it is nowhere near the toughest steel on the market. %160, 52100, not to mention L6; all are tougher and much more ductile than INFI. Don't get me wrong, INFI is some excellent stuff; but it is not the end all be all of steels; there's better stuff out there depending on application.

[kimber1911fan]

@RebelWrestler45

where did i call 3v stainless? but on that note infi steel is close to 154cm is stain resistance and is alot tougher than any other steel on the market.

[RebelWrestler45]

@kimber1911fan CPM 3V isn't stainless
