Yep I have so many knives yet my 2.5 inch esee izula does 99% of everything, everyday and on every animal. I use a 4-6" fillet knife or 6" flexable boning knife whne processing in my garage. But in the field the izula does it all. I just bought a white river caper knife (almost same as the izula) and love it as well.
Other than shelter building or similar needed camp, survival knives, all my knives are small under 3" as well.
Easier to work with, quicker to sharpen, safer to handle, easier to carry, cost less money, etc!
