Hi rasatter,
Good idea about using zip-ties on the luggage zippers when travelling, I will use that.
I think nail clippers are useful in the bush and carry a set in both my work truck and first aid kit. My hands/nails take a beating in the bush especially in the winter therefore I find nail clippers useful, they are also good for working on slivers and blisters.
I have damaged my teeth in the past biting through fishing line, I now attach nail clippers to my fishing vest to cut it.
