Also remembered that I have another folding bow saw, a Coghlan's that's also a 21" blade. The frame says "Made in Canada" and the blade "Sweden" FWIW. It's a little cheaper feeling, some of it's plastic and a bit more crude in design but when assembled the blade is taut and cuts fine. I would have assumed it was less a less expensive saw but I see it's $45 on Amazon.
There's a couple of things I like about it over the Sven. It folds open and just latches, no putting the bolt through and no wing nut to lose. Replacing the blade doesn't require removing roll pins. It's held in with a screw.
But when it's folded it's a little more bulky and relies on several rivets in its construction. Mine kind of falls open and it's not been heavily used. I don't care much for how the blade is kept in the frame while stowed. It relies on a finger tightened socket cap screw.
The Coghlan's weighs 346 grams and the Sven 377 grams (this is with my spare wing nut on the strap).
Pretty much two similar tools. I'm not sure why I have both because if I had one I wouldn't see any reason to buy the other, so maybe it was a gift situation.
