How have your tastes in fixed blades evolved over the years? What I mean is, have you found yourself preferring thinner blades or shorter blades as you use knives more?

As an example, I used to think a fixed blade should be a big heavy blade that can chop and pry and be unbreakable. Now I feel that when a knife is large and heavy enough to use as an axe, it tends to give up some other qualities that I find more useful.
