Recently, as i was cutting up a chicken:
"Wait, where'd that even come from? Youre not wearing a shirt. How were you..."
The full version is that i was wearing my knife in its sheath in the kitchen, but the sheath was sitting comfortably in my pocket (you know the part you put your belt through? on these jeans, theyre right near the pocket. So only about an inch of the handle was even visible). I was laying out the plates and cutting board and stuff, then he turned around for a second and picked up his cup. He turned back, and suddenly i have a knife in my hand, and im cutting the chicken. I wasnt wearing a shirt at the time, and i usually dont during the summer, so i guess i can see how knives miraculously appearing might be a bit surprising. However, come to think of it, if i werent into knives it really wouldnt occur to me that a sheath would sit pretty deep in your pocket, even if its on a belt.
