Depends on:
1.What the USPS, or Fedex, or UPS man brings.
2.What I'm doing to a car, truck, pressure washer that day.
3.What knife I have on me.
Today I opened a box, stripped a bunch of wire putting some more lights on my truck, and cleaned my fingernails.
A SAK Tinker was responsible for the first two, a Classic for the nails!
