Dennis,
As when considering any blade, the pertinent questions apply: What's the primary purpose of your EDC? Self defense? Tactical field use? Civilian utility knife uses like opening boxes, cartons, plastic bags, & mail? Do you want to carry larger blades? Is deployment speed going to be important? Is this going to be strictly a cutter/slicer or will it have to pry & hack as well? In any case, which one of his blades to carry will depend on your requirements & the limits you have to operate within.
If your circumstances require a shorter blade, I'd add Trace's LEO to the TTKK already mentioned and the Spook you like. I can vouch for the LEO handle (Warhawk style handle) being extremely comfortable and secure in the hand. For a larger blade, his Tempest at 6" blade would be pretty sweet, but be aware of the recurve blade considerations.
I've said it before and realize that I'm preaching to the choir on this, but Trace's craftsmanship and finish are top notch. Given the quality of workmanship and materials, his prices are very reasonable.
HTH,
Greg
