Ok, Ok! I can see this is a topic that causes all sort's of disagreements. In the interests of keeping the peace, can I point out to everyone that your tin has to contain all the bits that you CANNOT make easily. That means purification tablets, needles, emergency tinder, fire lighter etc. Any cutting edge you carry is going to be your back up to your back up to your back up. I should also point out that the original tins were designed for E&E. So the contents were picked for concealability as much as for their utility. Our requirements are somewhat different. In terms of knives, I have a scapel blade in mine and a swiss classic in my otterbox kit. And I am in deeeep [censored] if I ever have to resort to either of them.
