Great concept, but...
Before i took it out, i gave it a few good shakes to make sure the saw wouldn't come out, and it seemed to be ok. But the first few whacks i took at an actual piece of wood, the saw rattled inside the handle, came flying out, and refused to stay in. The magnet that holds the saw in was just too weak. So im guessing that it must not have been designed for chopping with the saw inside, but i guess its good for saving space on the move.
