When you're choosing a survival knife, there are a number of key points to look out for. Much will depend on your own particular needs and requirements, but some factors are very common.
Whatever you do, choose a knife which is made of top quality material. You don't want it to fail just when you need it most. Stainless steel or carbon steel are definitely the best choices - or a combination of these two materials would be equally acceptable.
The design of the blade should cater for a high degree of multi-functionality. You may also choose, depending upon your own requirements, fixed blade or folding blade.
You will certainly want a survival knife that is durable and rugged. Don't skimp on price - get a top quality knife, you may depend upon it some day.
