Yes sir, the only correct answer is that there is no correct answer. Which is precisely why it’s worthy of discussions like these!What true north wrote is the other part of the value equation. There is no question that the Busse in your example, has the better Heat Treat and can safely be called a lifetime knife. The question is whether that extra performance/value is necessary for what you do. Does a small knife need to be as tough as a Busse or CPK. In many cases that extra cost is not necessary. Up to you.
There really is no wrong answer here. It's just what level result you expect. You could argue that the $120 buck does not give me any advantage over a 20 dollar Mora.
