Today I´ve only cut tape, which I do often, so many things come in blister packs these days, how do people open them ?, I find a knife is best for that.
Open cartons, cut string, open cans, clean fingernails, cut fruit, slice bread, help my daughters and nephews with school projects, hobbies like whittling, etc.
Most people use diferent tools for diferent things, a cheff knife in the kitchen, a box cutter in the shop, a scissors at the office, etc. when much, if not all, can be done with a single tool, your EDC knife.
