I guess something general purpose, cutting,chopping and fine work, even digging. I was thinking of the MOD 1 knife but from all accounts it is excellent at chopping and splitting but lacks the delicate and fine edge required at times. Surely there must be a knife that combines all the elements needed in a survival situation. obvisiously everyone has their warry`s in regards to what knife is best and what to use, so lets hear them. Give me your knowledge.
