Pacific Salt, Endela and the Caribbean in SE all seem to have quite a following.
But there's one I suggest to everyone who has not tried one. One that will outcut any of the folders I listed.
The SE z-cut.

It is extremely thin. BD1N works well for SE, very quick and easy to touch up. It is one of Spydercos most affordable models. Being a kitchen knife most people will find more use for it than buying a 26th 3-3.5" folding knife.
Give one a shot. It will cut circles around most serrated folders for a fraction of the price.
I carry one every day at work and use one at home as well. Paired with a chef knife you'll have your bases covered outside major fileting and butchering tasks. Mine does everything from butterflying filets, slicing tomatos and bread, to breaking down cardboard. Handy little knives, I've got four!
