One of the first aid "tools" that I have seen in the past are "dykes" or wire cutters.
These are suggested to be used for removing the barbed end of a fishook when it becomes stuck in a finger, arm, etc. The idea being that the hook is pushed through the skin until the barb is clear of the meat and then nipped off, etc.

They are not something that would be carried all the time, perhaps only when going on an extended fishing trip.

Any suggestions on "other speciality tools" that would be tailored to a specific trip or activity. These are FAK items only, nothing totally extravagant.

One other question; are inflatable splints still used and if so, are they worth having in a group type kit, or are they just too bulky for what they do?
