In addition to those Victorinox SAKs already mentioned above, you may wish to consider a number of Wenger choices. In particular, since you mentioned that they need to be "...a pocket friendly size...", you should check out the Wengers that are 85mm long, along with the 91mm Vics already mentioned. I have a few of the 85mm Wengers and they're great (I also have many, many Vics). There are several 85mm Wenger models that have a wood saw, which makes them a very handy camp knife.
Shown below is the Wenger Evo 17, which is an 85mm SAK:
Victorinox makes an 84mm SAK called the Lumberjack that is a very "minimalist" SAK that also has a saw blade, as shown below:
If you want to consider larger SAKs, particularly if you'd like to consider a belt pouch instead of pocket carry, then the field widens considerably. There are a large number of 108mm and 110mm Vics with saws, as well as many 120mm Wengers. Those larger models are great for outdoors carry. The saws on the larger models are correspondingly larger, so they work better on larger pieces of wood.
Shown below is the 110mm Vic One-Hand Fireman model, for example. This is my personal favorite 110mm Vic.
