Your smallest "full size" knife.

+1 on the Izula II, it's a nice full handle and feels great. Also, here's a Koyote Convex EDC that's just awesome! (pictured with Scrap Yard Weiner Dog- another great blade!)

+1 for the Izula II. Might be worth to try.
Otherwise a Busse SAR 3, the blade is between an ESSE Izula and a ESSE 3 (I think it's 3.25") but with a longer handle than the Izula.

Blind horse just had their bushbaby as Jan. Special

Maybe Entrek badger or backup?

To me it seems that a classic Mora knife would fit your description perfecty. Light yet decent size and very capable.

Simple is good.

I'd say my Bk11 but I also have a Lester River Bushcraft knife with a 3" blade.

I always wanted a Murray Carter neck knife

Swamp Rat is doing pre-orders for their "rodent solution" which should fit the op's bill.

Mark Wohlwend has just posted these beauties up, might be another option to consider !

Specs are 3/32 steel.
Blade is 2.5 inches
Handle is 3.25 inches.

esse4, spyderco mule team w/my handles. Spyderco woodcraft mule w/my handle orange.
these are what i have in fixed blades in the 3 1/2 inch to the 4 1/2 inch esse. the spydercos provide more length for the handles than the esse.

another vote for the izula2 -- I have XL hands and it fits great.
here's a pic of my izzy 2 laid on top of my ESEE4 for comparison:

Another one to look at is the Koster BOB knife -- needs scales, but very affordable.
He also makes it with scales, but I don't remember the name of that model (and it costs a lot more)
This is one I put osage orange scales on and made a pouch sheath for:

I don't know if hawkbills are useful to you, but the CRKT Bear Claw has a great handle that fills your hand and follows the shape of your fingers.

For a compact knife with a full, four finger grip, I gotta recommend the Michael Morris (mykulmorris) Pee Wee. 7" OAL with a 4.25" handle. Blade height tops out at 7/8". MM is a great guy to deal with to boot.

Second choice would be a Bark River Woodland Special. In the sheath it disappears into a Carhartt coat pocket.

Izula ll !

 

[Div4gold]

The handle is only 2.5 inch's, blade 3 inch's. Made from an old file and ironwood. The fat handle gives a good grip.

My Michael Morris small fixed blade with 2 3/8" blade. 4 finger grip in picture with comparasion of regular 93mm Victorinox (Yeoman MK III yellow scales in this case):
