Rigor wrote a review of Gerber Exchange-A-Blade Saw w/ 2 Blades on February 7, 2007
This folding saw i very light an works out fine. Sadly the saw is to fragile. The blade is very easily bent an the connection between blade an shaft is loosening up.
If you are careful and are looking for a light saw this is a good product. If you (like me) has a more rough handling action I'd recommend something stronger.
