Do we expect too much from pocket knives?

A big leuko for doing the heavy cutting and a puko for the little jobs?

Yes, and the larger knife has the same grind/steel. I have a 8" blade version for example with ~1/16" thick stock. Top one here :

Looks 'taller' (edge to top edge) which makes me think beams and floor joists thicker (and thus stronger) in the direction that they will expericane load.
I cant remember off hand but i think its 2 times as thcik for 4 x as strong....need to look it up.
When i think about it the main forces will be 'perpendicular' cutting edge to spine in most CUTTING. On the otehr hand when people put twist and sideways loads on their knives (which to be honest is rather abusive, even if it CAN take the stress) then the knife will have to be built with a 'fatter' (side to side) blade like a lot of what i think of as pry-bar knives. I think a lot of the cheeper 'tactcal' mod's do this- leaving a knife that will usaly not cut very well. That said i've got thick blades sharp enugh to shave, but they still didnt cut too well for me since they had to push fat sides through the material.

Back to the point which was that the people who lived IN the wilds 24/7/365 had 2 tools for their tasks- not neccisarily because the one couldnt DO the otehrs job, but because it was easyer and worked better to have two.

Yes it is quadratic in thickness and linear in width. The Opinel is actually thicker in the spine but is full ground while the above knives have the traditional sabre/flat at about 9-11 degrees, depends on the model. None of them have significant full blade strength. You could easily break them all with just wrist strength with no real effort. They are so light that they simply don't see any significant impacts in chopping so they won't flex signficantly.

Sure, just like I use an axe when I cut down wood to burn and not an Opinel, but if I had to cut down a tree with an Opinel I could, it just takes a lot longer. I have actually cut a fairly amount of wood (built a shelter and such) with a blade which was ground like a straight razor, deep hollow ground, O1 at 63.5 HRC. It makes the Opinel look like a crude wedge. Now you have to be really careful with knives like that because it won't take much twisting to leave a big piece of the knife in the wood.

Generally why guys like Vivi do light chopping with an Opinel it isn't like they are making an arguement that if you need to clear a lot of brush you should leave the machete at home, just that it might not be worth taking a machete if all you want to do it cut a few skewers for a camp fire. There is also the arguement that you are learning how to prepare for the worst. Finally it could simply be a challenge.

I had to prepare a turkey recently and I used a Byrd Finch (size of a matchbox) to take off the wings, remove the legs, and cut off the thighs. It isn't the ideal knife for that and took more time than if I had used the Paramilitary but I would not have learned anything if I used the Paramiliary. The main drawback with the Finch is that the entire knife gets in the turkey so the pivot gets dirty.
