Just gotta mention Agawa Canyon’s Boreal21 bow saw….good example of kaizen, continual improvement of Bob Dustrude’s saw. Comes in at 480g (mine weighed 484g w/o blade, +43.7g w blade), a bit more $$ than the Dustrude saw. But it is a well thought out, engineered, and dependable saw.
You can view one seasoned user’s comparison here. Significantly heavier than the Suluk46, and many others mentioned, but this one cuts wood. Might consider for car camping if a 1lb saw is too heavy for your pack. But the design/engineering is awesome. Don’t have to return to the factory when “When the burner thinks it has overheated (whether YOU think it has or not!), it trips a shut-off valve that must be reset at the factory.”
