[quote I forgot to mention this before. If you get two of these kits, and take out the two knives and one tin foil roll, you can combine the rest of the contents into one of the supplied containers. [/quote]

Rather than do that: Buy two kit's and put them in separate locations in your survival kit. Gives you a lot of redundancy against lost.

Loss of 1 x 2 kit's = 50% loss of your fishing capability.
loss of 1 x 1 kit's = 100% loss.

Where possible dispersion of your kit's contents is always a good idea.
