I carried a knife of some sort everyday in high school from 82-86.Never no problems of any kind,teachers would ask in class who had a knife if they needed one,usually 7or 8 would be offered up.We used to trade knives at school w/some of the teachers,no problems then,no stabings,no threats,no murders.Nowadays i work in a federal building,and i still carry a knife and leatherman everyday to work.When i first started,my supervisor told me no knives of any kind were allowed.I showed her the federal law that said up tp 2.5 inch blade was allowed,she shut up about it,and im still carrying 6 yrs later.Guess who they come to everytime they need a pliers,or somehing cut....yup,me.Supervisor thinks the leatherman is cool beans now and has asked about getting her own.Just goes to show,if you let the sheeps see you doing the things knives were intended to do day in and day out their narrow little minds can absorb it and change....sometimes.
