FWIW, I think a lot of it depends on where someone lives, what they do, and how people in the same area react (i.e., do larger knives send locals into a panic.)
I think it can also depend on the knife itself. For example, if I am going to buy a big knife and use it for any sort of hacking or chopping, I would prefer a construction using one of the carbon steels that are strong and easy to sharpen due to the edge damage certain tasks will cause. Steels like A2, 3V, or L6/5150, 52100, etc. have considerable strength in regards to impact resistance, and so they can be used harder than your average cutlery-grade stainless, potentially shaping what that fixed blade knife can & will do versus cannot and should not do.
Finally, I think it depends on the task. If someone owns a very expensive fixed blade, they may or may not want to use it in the same manor as they would an axe, because of how much that type of usage can harm the finish. Additionally, cheap axes in good carbon steels are commonplace. But, an axe large enough to chop large pieces of wood may come with the cost of considerable size & weight to carry on long distances, where as a fixed blade that is capable of batoning can be a fraction of the weight or form factor of the axe. While the axe would be better if the task means chopping tons of wood, the fixed blade could handle smaller wood splitting tasks.
