Thanks Flatlander, good info.
First aid kits are business, just like lot of things, so they are there to “make you feel better” for some folks.
It is better to have few simple items with you but know very good how to use it, tourniquet is thing to use when everything else failed, when there is no other way to save life.
Most of the time direct pressure, and pressure bandaging works good, and you do not even need to have real medical items to do that, you can use what is available, of course I am not saying it is better to do it with dirty bandana and pieces of cloth, just example that knowledge counts more.
There is a feeling that lot of people will just at the first sign of bleeding pull tourniquet and apply it, just because they have it in their first aid kit, and it looks cool.
