That would be your opinion of Esee, not the opinion of Esee owners. And for all your big long posts filled with lots of info and big words I figured you would understand the physics behind why throwing a knife can be so devastating to said knife.
Oh I
do understand the physics, which is why I know their position is silly. Geometry, strength and toughness, and application of force. In order to break one of these knives, you need an inclusion either present in the steel from manufacturing or created via fracture and then propagate that fracture through sufficient application of force. At this geometry and these materials, that application of force is
significant if a flaw isn't already present. Batonning is far more stressful on the knife, hammering it into steel and concrete more so. Throwing? What do
you think is so stressful about throwing? Just what level of forces do you think you are generating? I'd love to see a break-down of your calculations because every attempt I've made has resulted in the same conclusion - it's a non-issue...
unless there's a flaw in the material. That's happened to Becker and Ethan has been very up-front about it, stating that he wishes he could guarantee every blade to be free from such defects that result in broken blades, but the price-increase would not be worth it to consumers, and the percentage of blades that fail is so low. Are Beckers fragile? I don't think so, but maybe 1 in 10,000 breaks? The other 9999 are sound.
It is
not my opinion that ESEE knives are fragile, it is
literally the opinion espoused by the owners, read:
http://eseeknives.com/warranty.htm
They are hardened to a higher Rockwell than throwing knives and will most likely break if thrown...
Their opinion is that every time a knife that is 3/16" or thicker at the spine and 0.030" at the edge and hardened as high as 55Rc is thrown, it "will most likely break". Every time it doesn't break, well that's a fluke, it'll break the next time! No? Well, it's coming, just you wait and see! 100X and nothing, not even a flake off the edge on a bad ricochet? Well it's coming, and you're an idiot and don't buy our knives!

OK.
Further:
Note: We do not warranty our 440C Stainless Steel knives from abuse. It should be noted that 440C is not as flexible as our carbon steels. Any excessive flexing will cause the knife to break.
ESEE knives are relatively soft (55-56Rc) spring steel. INFI, SR101, CPM-3V, 420HC are all hardened to >58Rc and at such thick geometries as these knives come in, none suffer ill affects from throwing that I've ever seen, further Rowen's 1095 seems to be just fine as well... yet the statement of the owners (quoted above) declaring their knives (and ALL knives not softer than theirs) to be fragile.
They go on to denigrate 440C steel and won't warranty knives made from it. Y'all realize that "excessive flexing" will cause ANY knife to break, right? That's usually what breaks knives - somebody gets part of the blade or edge stuck in something and it flexes until exceeding the UTS, that's how fractures propagate. What does Ray Ennis say about using 440C HT'd to 58Rc in Entrek knives?:

If this Entrek USA knife fails for any reason it will be repaired or replaced at the option of Entrek USA at no cost to the original owner.
I'm not down on Rowen's manufacturing, I think they're plenty tough, and I love those Junglas-throwing vids :thumbup: (most of which had comments disabled due to flaming by ESEE fanboys). I just don't get why the ESEE-owners - per their official warranty declarations and statements they've made on forums - are so concerned about the fragility of the knives. Like Cobalt said, if there was really a problem with the steel, we'd know by now, right? If it turns out that 1 in 10000 ESEE knives contain a flaw in the steel that results in a broken knife when it is thrown, does that make the other 9999 fragile? Does that make EVERY knife made by EVERY manufacturer fragile? To assert such is irrational, that's all.
