Usual disclaimer: I have neither affiliation with or experience with the "Fisherman's Friend" cough drop company in any way.
I took a "Fisherman's Friend" tin box (hinged) and have placed basic fishing equipment in it. Hooks of various sizes, swivels, a cork, and 20 ft of monofilament line, has hardly taken up the space that the box has within it.
I may go ahead and include a yo-yo fishing reel later since there is sufficient room for one, or I may find something more useful to add to it.
This small kit has gone into my BoB (the 1 supplied to allow me to work my way through 700-800 miles of countryside in order to get home if TSHTF while I'm on a towboat working).
IRT the other thread about the Family Friendly SHTF plan, I have to have this special plan besides the "Bugging In" and the Bugging Out" plans in order to have all reasonable contingencies/situations covered.
At the moment, when I deploy to my towboat, I am carrying: my EDC, a PSK, and a BoB. I have reduced the redundancy factors dramatically but I'm still packing about 50LBS altogether.
I have 40' of fly-fishing backing line in mine. It's much easier to handle than monofilament.
20 medium hooks. For setting long lines.
Assorted split shot and swivels.
2 large gaff hooks.
2 silicon gigs. For hobo fishing.
2 wire leaders.
Tip: put your hooks on safety pins. Makes them much easier to handle.
As a general rule: You cannot have too many hooks and the more line you have the better.
Thats just a pocket kit. I have a slightly larger kit that goes in my bag. One thing worth having is hooks already on line. They are commercially available for a couple of dollars for 10.
