right now i have a great digging tool, unfortunately, its also a scary looking weapon (a 15" total length heavy knife) that im afraid of people seeing it so i keep it as hidden as possible. i need a good digger for public places that doesnt look so intimidating. any suggestions? something that will let me dig a nice, clean plug so i can walk away with the ground looking exactly as i found it. something heavy duty because im brutal on my equipment. my knife fits the bill except for its major drawback of appearance.
