I don't have that many knives comparing to many, but before setting to one "ideal" size I experimented with different sizes, especially gyutos. For my uses, 24cm is my ideal size and I have 3. I used to own 6 but simply it was overkill.
Still I am trying to scale down and balance my collection between knives for me and knives that the family is allowed to use.
