I was recently in the thrift store and asked the guy if he had a hack saw. We both saw this saw at the same time and he handed it over to me. Turns out it has two hack blades and a wood blade. I think this is one of those brand name pack saws, but there are no identifying marks. After cleaning up two of the three blades, one of them says Made in Sweden and a brand name, but I couldn't make it out. Any idea what it is? For $4.99, this was a pretty good buy. Very light weight and versatile. The body is aluminum and the blades store in the handle; you flip them out like a pocket knife.
All three blades looked like this on both sides.
and after.
