Broken full flat ground during batoning

I can harvest more wood with a folding saw and a large fixed blade, than you can with just a axe/hatchet alone. If I can’t baton with a knife, then it’s no good for me. Take this for what you think it’s worth.

What was the test that led to this conclusion?

My own personal tests. I used to be an axe and hatchet guy long ago. Many Gransfors, Collin’s and Hultafors in the stable. I had a close call and almost chopped my lower leg off. I remembered seeing my dad baton big wood into little wood when I was a kid and decided to take that route. A Silky big boy can cut more log sections than your axe can at a much faster rate. Then, it’s just a matter of batoning those rounds down into kindling. Much more wood in a much safer manner. Ask EngrSorenson EngrSorenson .

Of course, this is all in the context of backpack camping and what we can carry in/out of the woods.

Is there a video of this to compare the technique to using an axe?

and yet ESEE's have jimping and a finger choil and can withstand beatings.
It's possible to design a knife that incorporates stress risers that is still robust enough for OP's needs.

In fact... to your point about bridges... that's why engineers design to a "factor of safety". do the math that meets the needs, then overbuild 3x what you needed.

How jimping is cut matters. Rounded valleys vs V valleys, the V will cause a crack and it will have a catastrophic failure when it goes. It's ok to have jimping, just properly machined or cut jimping

That’s true, but any jimping introduces a radius which represents a stress concentration. The bigger the radius, the lower the concentration, but it’s still there.

Accidents can happen to anyone, even grammatical ones. Nobody is incompetent or inept here, just a different way to accomplish the same thing.

I've read...........When, jimping is cut matters too

When we cut 12560 armor into parts that go on strykers and tanks, there's radiused features. A proper transition when changing angles is the difference between a part that fails when you need it most and one that lasts a lifetime. Spreading the stress vs concentrating it. Works for vehicles that run over ieds and take rpg hits

A knife blade had never spontaneously failed on it's own.

Give it time enough....



ANYWAY, as I said, blades fail due to - or their failure is greatly enhanced by - specific structural defects, most prevalent of which are surface defects - such as badly executed jimping.
