they make a very sweet knife with a serrated blade ( a good thing), a scissors, pliers, and both screwdrivers, that come in at 4.1oz
i have one of these and it is a treat. big enough to clean a real fish. pliers to pull nose hairs. screwdrivers to open ammo cans and whatever else i decide to open/repair/modify. amazon had it for about 30 bucks. it was not easy to find this exact perfect model.
as far as "not needing" tools" ... whatever.
if one has the skill, but neglects to have the tools, that seems like a waste of a resource.
so : one shows up at a problem, unless one has tools, they are still bringing their needs and wants, but no "solutions" to the table.
i have at times carried a small digital voltmeter, because being able to fix things means being able to deliver value. and if you are thirsty/hungry/cold, and somebody (who has beer/food/fire) has something broke, it's nice to be able to return the favor.
ohh, what can tools fix ??
