Le rouge et le noir...I would just guess you like red and black, just a shot in the dark? Or Stendahl. (actually am guessing those are orange, but color shift with camera?)

The yellow Pacific Salt is more a, "Is that a banana in your pocket or...a banana?"

Truly, they near always are very flat and concealable, but I love the Manbug and Ladybug for near everything, small shirtpocket knives which do big knife cutting. What color is the Manbug, Steve?
