I have all my knives in a lockable display case, except one of my Police knives was out that I had just sharpened.
One of my sister's friends comes over and sees a poster of Carmen Electra on my wall and sees the knife sitting on my nightstand. He picks it up, opens it up and starts waving it around on certain areas of Carmen's body saying "this area is nice" and pointing with it.
I told him if he ****ed anything up, the knife or the poster I was gonna beat the hell out of him. After I said that about three more times he closes the knife with his index finger in the area where the blade would fold down. I said.. "uh you just cut yourself" He said "no I didn't"
I then said "You don't know how sharp it is" and he looked at his finger and it was gushing blood basically, there's some on the carpet and in the sink. He might need stitches.
And that folks is why you get a locked display case...in case idiots come over.
