And another query about wire saws: How do you keep the wire saw "blade" from destroying other items in a tightly-packed pocket PSK? I can see where mine could punch or wear holes in the aluminum foil (not that big a deal), the water bag (very big deal) and other items it comes into contact with. Is the key careful packing or enclosing the wire in something? If so, what? <img src="images/graemlins/confused.gif" alt="" />
