Parcel Hook:
1) Tighten thin ropes when tying, especially when hands are wet
2) I saw it on Moonrise Kingdom(a dark humor art film, about a young couple decided to run away and get married at 12), Edward Norton as a Scout master, use this hook to open a tent zip from the outside. If the zip tab can only be pulled from inside and up(he open the zip by putting his hand in tent, hooking onto the zip tab and lift up), then it is actually a good use.
3) Lifting hot pot off the fire
4) Maybe pulling rusty or sharp wires out of the way? But never have that opportunity...:indecisiveness:
Corkscrew
1) Besides what obvious, you could untie very very tight knot with this...only tried this a few times in many years, but it did work. :encouragement:
