Wanted to do a tiny knife shootout so here ya go, enjoy. 
Here are the contenders: JK fire kit knife, Turley 23 and the Buck Smidgeon. Note how similar the JK and Turley are, I wasn't even thinking of this when I purchased the Turley, I reckon they'd be considered roach bellies.
Spine shot. L-R: Buck, JK, Turley, as you can see the Turley is the thickest of the group followed by the JK then the Buck.
First test, notches.
JK - Great all around knife, slices wonderfully, comfortable handles(as much as I get to hold anyway), performed well for notches.
Turley - Took a nice sharp edge, slices well. Feels fine at first while using but gets uncomfortable quickly. When batonning into the wood for make the first slice it wants to spread the wood apart very quickly due to the thick grind. Overall it did well for notches.
Buck - Sliced great with the thin grind. Jimping absolutely destroyed my thumb, honestly I didn't even wanna finish this with this knife, it was painful. Overall impressions: I'd use it if it were all I had.
Batonning.
JK - Did as well as can be expected for such a tiny knife, shock from the baton didn't hurt, no damage and got the job done.
Turley - Shock while batonning hurt my hand a bit but its thick edge helped in batonning, did fine, as above no damage.
Buck - Catastrophic failure, broke batonning the 2nd piece. Was batonning straight, easily splittable wood with no knots.
Drilling.
Turley - I was able to finish the hole, wasn't very quick due to the blade shape, gets alot of belly quickly. Slipped while drilling and cut the #### out of myself. Poor thumb, blister and a cut, need to give this fella a break.
JK - As above, finished the whole not too quick. Handle was a bit more comfortable to use but otherwise identical.
Fishing Spear.
JK - Got the job done but took forever. Being comfortable to use was a plus.
Turley - This knife is sharper than the JK at this point so it made for a better carver.
Batonning to length.
Starting the spear tines.
Spear Finished.
Finished spear with the Turley.
Overall impressions. They worked, for the most part. If I had to use one on a regular basis I would choose the JK, as it's more comfortable, of course if I needed one specifically for a small survival kit I would go with the Turley, it's a bit less comfortable but its alot thinner and can be stowed easier.
That's it for now, if you'd like to see some specific tests I'll be more than happy.
ETA: Positive about not having handles on the Turley: I can beat at any point on the knife and not worry about breaking handle scales.
