Since it is raining and I am bored - a discussion of the most likely usage of your EDC carry knife. Mine is a Spyderco something.
1. The war against Amazon packages!
2. Opening packages of food in those plastic envelopes that I can't pull open after 'tearing here'. Note wife cannot see this!
3. Plumber is screwing with sump pump and needs to cut some foam tubing and can't find his utility knife, asks me if I have something. Smoothly deploy knife and scare him a bit. He asks - told him it was knife class.
4. Given a talk to TX Bar on appearance issues. Sitting at the speakers table. Open my tableware package to eat my rubber chicken. No knife, would have to make a fuss to get one. Deploy knife.
Any other real world uses that suggest why the EDC knife is important!?
