Yes, the blades usually stay folded in, but metal edges, corners, and wingnuts can damage packliners, lightweight stuff sacks, and other contents in your pack. Cover those hazards with a waxed canvas Saw Bag! The top flap folds over and ties to accommodate different sized saws. The Short Saw Bag will work for up to a 25in saw, the Long will work for up to a 30in saw.
