I keep 25' 6# test and 5-6 small hooks in the handle of my BK10 knife. I fished with a similar setup on 3 separate occasions years ago while backpacking. The bait, if I recall, was small grasshoppers and worms. I caught nothing on two occasions and two small trout (probably planters) on the other. Not exactly a ringing endorsement I know, but I was just successful enough that I have carried a very minimal amount of fishing gear with me while in the outdoors ever since. Some leader and a few hooks take up little space and weigh (and cost) practically nothing.
