I never had or used a Sven Saw, I heard that they were not very good for bigger diameter wood. Just by looking at them I knew they wouldn’t be up to some portage clearing or campsite clearing.
I did buy a Schmitz Pack Saw made in Maine. I saw one in a canoe outfitters store in Ely, Minnesotan. I thought “Hey, I could make one, it’s just like the buck saw my dad has on the farm, that we used to buck up firewood.” I drew a rough sketch of of it on an envelope I had in the truck and forgot about it. I had a Collins Hudson Bay axe, probable didn’t need no stinking saws. A few weeks later I was back in that same store, had money burning a hole in my back pocket, so I bought that saw. Every time someone that sees and uses that saw on a trip they really like it. I used it so much that when it got dull I took it to a Vietnamese man in the back of a Vietnamese Restaurant that advertised saw sharpening. When I came back to get it he told me to never bring it back. It was too hard to sharpen, I wouldn’t take my money for sharpening it either, which was odd, although we did share our stories about his homeland.
Since then I have made copies of the original that I have given to friends. I made a 30 inch once for a canoe trip to a favorite campsite, that had two big trees blow over in a 100 mile an hour straight line wind storm that caused a lot of damage, in the BWCA many years ago. That saw made it fairly easy to buck up that big White Pine and its fellow White Cedar, that had made the flattest tent spot unusable. Made some really good firewood too.
