Step 1: Tool up
most things are light and cheap.
1. a plier multitool= either a gerber, leatherman or SOG multitool, the others are to cheap and break with a simple task. (i use a leatherman juice s2... the only one without a worthless quark screw.)
2. A good (pocket) knife= now i dont mean a $500 knife but a good one. buck, gerber, SOG, or Kershaw, or the traditional swiss army knife. Now a good base is to check the metel content and how solid the knife is. I have had good luck with bucks like the Pilot wich is like 13 bucks from cabelas. I say away from the swiss army beacuse they lose a edge fast, also the pocket clip on other knifes are nice.
3. random strps of metel= this is pretty much a option but i keep small allen wrenches and some strips of metel for .....lockpicking..... (dont think less of me i use it only for good) and i have some wound thin wire.
