There are many things to consider when choosing a survival MT, but I would like to address one tool, the saw. I've EDC'd a CS4 for quite a few years now and find it to be a very useful tool despite some the the Juice series' shortcomings. The saw on the CS4 out preforms its size. When I compared the CS4's saw to the saw on the larger Wave I got a surprise. While the saw on the Wave is larger than the saw on the CS4, the row of saw teeth is the same length on both saws. I don't have any experience with the saws on the other models mentioned in this thread, but I can tell you that I can cut through a 2 3/4 inch branch with the 2 3/4 inch saw on a CS4.
Heinz mate, put a swisscard in your first aid kit!
I did this as a nice little back-up SAK; my Pygmy Huntsman mod (84mm).(Image removed from quote.)
Well my one is by one of the old school modders; Scibeer.(Image removed from quote.)However there are a few guys on the site who are making them today.
