the need for a metal cutting tool in a GHB scenario caused me to include a section of hacksaw blade with my EDC selections... additionally I carry an AxisLock Benchmade folder that has a metal pocket clip and lanyard hole.... if you run a split key ring through both the hole of the blade and knife, and swivel the hacksaw blade through the belt clip, you have a pretty secure handle for the saw...a wood cutting saw with hole would work also... if you use a small key ring the same task can be done with a multitool plier like the small Leatherman PS4
