Ditto on this guy, I use it for sledding in the winter & for creeking, great tool.Do a web search on "Sabre Cut Saw" -- Next best thing to having a chain saw.
Yeah, I wouldn't suggest it for wood; although I've found it works better on wet wood that dry wood. I have used it in the field for 6"-8" diameter underwater strainers. Overall, though, a handsaw works better for wood and I carry one of those too.To the guy that wrote about the wire saw from home depot - I actually bought one of those same exact saws and I tested it at home and had a lot of difficultly with it. It may cut through plastic really well (because it's meant to cut through pvc) but it doesn't cut through wood very well.
