I carry my nice folder well cuz I want too. Its not commen sense, as and SA/IT guy if I need to open 100 pc's I will use a box cutter for the job, but if I need to open 3 I'll use my sebbie or ddr or strider etc. etc. Knives are nice for other things I cut like zip ties, sandwiches etc. I use my several hundred dollar knives cuz I can more than anything else, and I dont feel bad about it. I see your point about using a box cutter and they are fantastic for what they are for, but there is many a circumstance either in the office or out camping that I want a knife and will use it.
