I carry a small slipjoint that I use for most tasks at work when I need a knife. I don't feel the need for everyone to know what I'm carrying. It won't ever be to your benefit to be known as "the guy with the big knife" by your office co-workers.
Any of you have a concealed weapons permit? Do you wear a t-shirt to work that says "I'm carrying a concealed weapon"? I didn't think so.
Discretion is rarely the wrong choice.
I was mowing my yard about 10 years ago when one of my neighbor kids (a former student) and a stranger came strolling across the lawn. I shut down the mower (rider) to talk to them when up out of the blue the stranger reaches into his pocket, whips out a 5" flea market tactical and snaps the blade open. He then gives me that "I'm a badass punk" look and proceeds to make a big show of cleaning his fingernails. All this before he has ever spoken a single word.
He never knew just quite how close he came to being shot to death in my front yard. I was still on the mower so I couldn't move away. There's no doubt he could have stabbed me if he had wanted, and there was no doubt I had already decided to shoot. Fortunately for us both he didn't take the last step forward to close the distance and so I didn't. Mind you this all took less than two seconds from the time he started drawing the knife to the time I knew he was just showing off for his friend. Only momentary disbelief (why is he pulling a knife on me?) and slow reflexes on my part saved him, and saved me from killing a kid for nothing more than being a dumb*** show-off. Somebody who was in 'condition yellow' all the time undoubtedly would have shot him.
I still get a cold shiver when I remember this incident-- I can still see that big blade opening and remember thinking "I'm about to be stabbed!" -- like it was happening in slow motion. Please, God, let me never come that close to killing someone ever again.
A lack of discretion almost cost that kid everything. Be careful when and where you "whip it out".
