I like tools, so I have things like hammers and very sharp machetes scattered all around the house, even if the guns are locked up. Sort of like knicknacks or stuff you have on the coffee table to play with. Another nice thing is a couple of cans of that bee & wasp spray that shoots a huge jet about 15 feet. That crap is kinda nasty. Haven’t tried spraying it over top of a lighted BIC lighter, though that works well with a can of Ether starting fluid.
I posted about the wasp spray before reading your post. Had a friend who swore by having a can in the car at all times.
I wouldn’t hestiate to use it if that’s all I had.
