I have one of these also. I bought it at an outlet store for something like $5. It was labeled as "What-A-Saw" and came with three blades (green wood, dry wood, and metal.) I replaced the green wood blade once. There are better designs but it gets the job done.Years ago I was gifted a Coghlan folding saw and have never really needed to use anything else. I keep meaning to replace the blade but it keeps on ripping thru anything I throw at it. The one downside to the design is the triangular frame. It'll only handle up to a certain circumference of log before bottoming out still in the cut.
