I bought a foldable saw at the dollar store for 2 dollars. It's of course some cheap Chinese stuff, but boy, I'm very pleased with it! It's about 9", and sharp as hell. I've cut several 6" diameter logs with it, and a large number of smaller ones. It broke after all the use and abuse. So I bought a new one, for again 2 dollar. I'll have to go through a lot of these cheap saws, before I come even close to the price of a foldable saw of a real brand. And I won't be upset if I lose or break one, because it was so cheap.
