I have this one. It works great, is compact when folded, and light to carry. Agwa Canyon
May I suggest something different for wood cutting. Agawa Canyon - BOREAL21 Folding Bow Saw is very light and can do a lot larger wood than what you are looking at. From experience backpacking I have found that I never use my hatchet with a folding bow saw around. And that bow saw is amazing.
