Some of the guys I work with carry leathermans and will wip them out for any reason , I DON'T carry one for the reason stated above , i work around TOO much live power AND the leatherman tool are FAR from the best ,
As to that knife shaped slab of steel that NBN showed , in the marines , in the field , newbys would have some thing like that , and learn REAL quick that it was useless and heavy , I ' ll take a few bics of some USEfull field blades , hell I 'll lay out ALL my blades for comment .
