Like I said, I don't.....but the Misses doesn't like freaking the average person out. Its easier to use a smaller knife, keep the PHRASECENSOREDPOSTERSHOULDKNOWBETTER. calm and the Misses happy......
On a side note I still remember "losing" a cold steel voyager, 5" blade at Universal Studios Orlando.... The look at lost and found from the clerk was great I still remember describing it. When I got to the "5 inch blade" part he stopped me cold, walked to the back and returned my knife to me. His words "what the hell you need with such a large knife in here for? Hunting?" I just replied "nope, but if I wanted to its always nice to know I could"
