Teller looked for remote applications for the weapon he invented. All of these are examples of the ways in which we are affected by the tools we create. A tool is an instrumentality for the accomplishment of a particular goal. Scuba gear permits me to break the bounds of gravity while visiting places otherwise inaccessible to me. If cars were considered emergency vehicles, to be kept parked in the driveway against the possibility of a disaster requiring evacuation, we would naturally long to drive them.
Guns are tools.
I have never hunted, but I enjoy eating venision, and I raise no issue, legal, practical or ethical, with this particular instance of tool use. At least some of the people who keep these weapons around have thoughts about using them to kill humans. To put it as bluntly as I can, I think that the ownership of handguns is connected in some people with a worldview which divides our fellows into categories of people who can and cannot be shot with them. An unused handgun, kept for contingencies, is an unrealized potentiality similar to scuba gear kept in the closet or an undriven jeep. Humans want to use the tools they love, and the complete fulfillment of the handgun involves the killing of another human being.
