Step 2: The knife
You can make a knife but i find this to be a time consuming effort and is nearly pointless compared to some of the knives you can find on the market. i will however put a link in just incase you were curious with this instructable
I personally always carry a swiss army knife that has a lock on it whenever i go camping, you could however use a bog standard swiss army knife without a lock: upside is it does more stuff (you could probably find one out there with and umbrella on it) downside is you have to be careful because it wont lock. on the other hand a simple lock knife without any add ons is good: upside is it's light weight and simple, downside is there is nothing on there like a can opener or a fish scaler etc. If you really want to go over the top and do infact find yourself stuck in a particularly dense part of the woods/jungle you may want to have a machete handy. i got one whilst i was in uganda and i havent regreted it since.
regarding the machete my parents beg to differ....
