With the awl having a rather steep chisel grind, it will tend to bite and wander to the cutting side.
-For clamshells I prefer a Pruner blade. You can get the tip to press through by "rocking/leveraging it in and the recurve holds the plastic.
That being said, I would much prefer a Pruner over an awl for a general purpose knife combination. Especially a Clip/Pruner combo!
Belly: check!
Recurve: check!
Straight edge: check 2x!
Nice sharp utility point: check 2x!
On top of that, both can be thin enough to excel at their respective tasks.
The clip will be a Fantastic slicer, and the heel wouldn't have to worry about flexing or breaking when choking up for close work.
The pruner would be great for detail oriented cuts, leather, fabrics and other soft material (pallet wrap) is where it shines. It works well for detail and inside cuts in wood for whittling. The blade hasn't been seen (iirc) on a bladeforums knife. Due to the nature of the kick being Just longer than the point, it can be buried far for comfort while using the main.

neal: it is still a bit out as I still have to acquire things like the pivot barrels and such. But I will be doing a thread on it when it (eventually) is completed.
