In building our trail, we brought the Trail Blazer along with us on runs. Each time we went out, we removed a blowdown or two from our new trail. It has all the power of a common bow saw, but collapses down to 3 by 15 inches in your pack. And at 9.5 ounces, it was never a burden to carry. We also liked the comfy foam handle and the fact that the blade was easy to replace with parts online when it got dull.
Good safety tip from the California Parks Department: When using a bow saw, cut branches as close to a trunk as possible. Otherwise, they tend to wiggle throw the saw toward your hand.
