I note that there are a few newbies voting for sawteeth. I think that it is very important that you realize that the sawteeth on RMKs do not have an offset. They are not intended for cutting wood and making clean cuts. Without the offset, the sawteeth can bind on deeper cuts and will make a gosh-awful mess. Other than as an emergency ripping tool, it is my personal opinion that sawteeth serve no purpose on an outdoor knife. Of course, opinions vary.....
I have to, respectfully, disagree. While the sawteeth won't do you any good felling trees or cutting firewood, they work quite well for cutting small branches. Anything much thicker than the blade is tall and you need to approach the cut from top and bottom, but the do get the job done. Making notches is also another use where the RMK sawteeth perform well. Don't think of them as a replacement for a bow saw or folding saw, but, within the proper parameters I find myself using them often enough in the woods to reserve an option for them....
