I'm not obsessive about wire saws, but ... Mine came with two enormous metal split rings to use to pull the saw back-and-forth. I substituted two smaller pull rings so it would fit in my mini-PSK Altoids tin. But in studying the kits Doug has reviewed, I notice that most of them don't include ANY pull rings, which means you can't use the saw until you improvise something. I can see a lot of arguments for being able to cut your way out of or through something in a hurry, so this deletion of the pull rings puzzles me. What do some of you do when packing the wire saw in your PSK - pull rings, no pull rings, or something else?
