I live in a relative urban area and often work in my shop at night, as many of you do. My dog, a Great Dane/Lab, is usually in the shop with me, but she would lick any intruder and expect rubs in return. Have you ever wondered what tool you would grab if an intruder entered your shop? My Japanese saw hangs on a wall, or maybe a 1" chisel. What would you grab in a moment's notice to defend yourself? Ok, if the dude had a gun, I would simply give up.
