These little guys are only US$13.95 each from CountyComm (or sometimes available from Drop for US$26 per pair. They weigh only 8 grams each. It is easy to think of a circumstance that you might need one of these. All you would need would be some line (eg from your repair kit) and you will soon have fresh fish for breakfast! Usually I use my own DIY fishing kit which weighs just one ounce (30 grams).
Then again you might have locked yourself out of your house and need a handy set of lock picks!
