Here are a couple that I would recommend...
I have not "sorted" these folders. The small Sebbie is too short in the grip (less than 4") to fit in my hand. The thickness of the ti slabs is about 0.050" (total) less than the large Sebbie, so I would guess the small grip width is about 0.400" or so. As a matter of interest, the Large Sebenza is a little too long in the grip for my hand also. I'm one of those "in-betweeners" who loves CRK, but really needs a "mid-sized" Sebenza...which doesn't exist.
I have carried CRK large Sebbies and Zaans for several yrs, but this year I am carrying the Southard AVO mid-tech, which fits me to a "t." It is a flipper, but I don't mind a flipper, as that becomes transparent to me in use. I really enjoy the AVO...it's a great knife at a CRK price...
The "sweet spot" for my hand size (large) is about 0.450-0.460" thick handle, and about 4.5" closed grip length. I have owned all of the below at one point, although most of them are gone now or replaced by something else.
From what I must "guess"... you might check out the Spyderco Gayle Bradley, the Spyderco Paramilitary 2 for 3.3"-3.5" blade lengths. Perhaps a Strider SnG might pull your strings also for a more tactical look and feel.
A very excellent folder, blade about 2.8" or so, is the Spyderco TECHNO. Small knife; capable of heavy work.
You will see that I don't have the closed grip lengths on these knives, but you can check out the detailed specs at BladeHQ, KnifeWorks, or many other popular knife-shops that support our forum.
