reasons you would want a razor sharp edge: processing small game/food, blisters/first aid,
reasons you would not want a razor sharp edge: not durable, won't stay razor sharp long if you use it,
you want your knife's steel and edge geometry to be based on how you plan to use it, and if the size/precision of things you need to do is very wide you might need more than one cutting implement.
for example i bring something like this for when i need a razor sharp edge, which gives me 4 factory fresh razor sharp edges (2x full blades) and instead of worrying about sharpening them i can just replace them. it weighs only a few grams and its small enough to forget about in your kitchen/medical kit. there's all kinds of different styles of blades and holders for these things.
when i need a slightly bigger knife i bring a little opinel because it doesn't look scary on the trail, floats, and gets the job done for cutlery and cutting cordage. small knife beater things.
if i need a bigger knife i bring a fixed blade or a machete with a blunter edge that i can literally sharpen with a rock if i need to. sometimes i need a big knife sometimes i don't.
the steels i choose have to be ones that don't rust because its very humid where i live. if it wasn't i would pick softer ones that are easier to sharpen in the field in improvised conditions even if it meant they don't hold an edge as long. this is just an example of the thought process i go through when deciding what knives (or saws) to use /out/ its going to be different for everyone.
