I have a 3"x2"x3/4" mints tin that I have stocked with:
1 spark-lite.
1 20mm button compass.
5 Tinder-Quick.
1 6' length monofilament with hook and sinker. As a ready use fishing line.
8' 2mm braided cord. About a 75lb breaking strain.
2 MP1 tablets.
10 British Army issue chlorine tablets.
20' braided fishing line. 20lb test.
6 hooks and split shot. Assorted sizes.
1 X-acto blade,
1 sewing needle, sail-makers.
6' high grade sewing thread.

Its held closed/together by 4 rubber ranger bands that are also extra tinder.

I put it together initially as an intellectual exercise after watching Bear Grylls (Yes, He That You All Hate). As a very light weight, pocket of your water bottle pouch, suppliment to carrying a Water bottle, mug, knife paracord and flint.

Won't replace my RSK, but then it's not intended to.


Thats my take on the hollow handled knife
