Over the years I have used both a Wy saw and a Gerber folding saw. Both work great but I consider them to be a little too big and heavy to really warrant packing on a backcountry trip. Is there anything better out there that is light and compact? The only reason why I think I might need it would be to cut out a skull cap. Is it worth packing any sort of saw for just that task alone? I realize ditching the skull doesn't save that much weight, but it might be worth it if the saw required to do so only weighed a few ounces. Thoughts?
