Either bow saw, Laplander, or Sven, I think here is where you must make a decision of what you intend to use the tool for. The Sven has the advantage over the Laplander in the size of tree limb you can reasonably cut. It would seem the Sven is better suited for cutting pieces for a structure, not just firewood.I buy bow saws and blades. Cheap, light, cut fast, and could be sharpened if needed. As an experiment I cut a cord of firewood (a real cord, not a face cord) in a day with one. Of course, it was pieces 4’ long and less than 8” diameter. It took about 5 hours.
Bow saw blades can also be used to cut their own frame if necessary.
