3V is some SERIOUS steel! (video)

[bdmicarta]

I was impressed by hammering the blade several inches into soft steel, even though I know that it should work. But hanging the weight off of the handle didn't seem that unusual. I calculated the approximate maximum bending stress in the blade and it was about what I would expect most hardened steels to handle. And the point of maximum bending stress was at a point in the blade where there weren't any discontinuities or holes or notches so the increased toughness of 3V wasn't a factor. If you look carefully at the test they hung the chain relatively close to the end of their support. It would have been a better test if they had hung the chain closer to the butt end of the handle.

OK, I'll try to explain this one more time. Think of your average cold chisel approx. .75" wide. Now think of a .75" section of that blade and add a handle to the spine oriented the same way as a chisel. I promise you there will be very little difference in the thickness of either when measured the same distance from the edge.
I don't have video to prove it (don't even own a video camera) but I have done this before with simple carbon steels back when I first started making knives and doing my own heat treating. I have destroyed dozens of blades in various steels, in various ways, in order to see what a given steel, at a certain hardness & geometry will and will not do. I have no agenda or anything to prove. Just telling it like it is. I'm not telling you what I think, I'm telling you what I know.
If you don't wanna believe any of this, feel free to do your own testing and report the results.

hey man it's cool. nobody is angry here :/

I hear ya buddy, no anger here either. Black & white letters on a computer sceen don't allow us to convey any emotion in our statements. I believe that's why a lot of these threads go south when the same threads held in a face to face conversation would be all laughs fun discussion. If I can ever help you with anything, just let me know.

Whoa, 3v on a thin blade :thumbup:

hey Shawn, actually this Field knife is 3/16" thick, I like to consider <1/8" as a thin knife.
The Carothers field knife is however properly sharpened and will push cut paper as delivered.

You are an accomplished tester, you know that a thin slice of tomato easily moves "out of the way", just like paper does.
I just got one of these and will do some testing on it and attempt to see the practical use of 3v
