The UnZipper Robot Tool is the ultimate answer for unattended bag calls. Drive the robot to the bag, reach over and down, and use the UnZipper to cut the bag wide open.
The UnZipper will turn “tactical” backpacks and sturdy, expensive luggage alike into shreds.
Consumables: The UnZipper uses standard curved utility knife blades, available at hardware stores, and tips made for arrow heads, available from sporting goods stores.
