Back when I carried a large RUKUS, I was at my son's end of baseball season team celebration. Someone brought a sheet cake to the park we were using, but no one brought a knife or serving utensil.
Discretely pulled the RUKUS, rinsed and dried it at a nearby water fountain, closed it again and offered to cut up the cake. The mom who brought it absolutely freaked at the sight of the CLOSED knife. "Why do you carry a weapon like that around?" I guess then was when I decided not to tell her about the Ruger LCR in my ankle holster.
"Please feel free to claw pieces of cake out with your fingers."
Thankfully, her husband interjected, "He brought a knife that you didn't. He's had it at every game this season and this is the first time I have seen more than the clip."
Seeing no viable alternative, she relented. Later, her husband asked to see the RUKUS. When I saw him next season he had a Kershaw Blur.
