If you happen to see me out and about more often than not I'll be wearing a kilt. I have to wear pants at work and enjoy the comfort of kilts when I am able. I have a couple utilikilts and they are super comfy plus they have pockets big enough for all my stuff.
In general I don't leave the house without a minimum amount of gear. In the prepper community this is referred to as Every Day Carry (EDC). A Leatherman, a knife, a flashlight, a bandana and a lighter are standard items I have in my pockets every day. It's amazing how often I use most of the items. When I'm suited up at work I carry a little folding knife. On my kilt I carry a short fixed blade CRKT knife. It rests in a sheath I made myself that covers the entire blade and 2/3 of the handle. The blade is around 3" and the handle maybe 5". It's a perfect utility size, a grip that's easy to hold and a short sturdy blade.
I've had this knife on my sheath every time I leave the house in a kilt. I figure I've been in restaurants and bars 250 times with this particular knife and never had a problem. Well, until last night. I went to the St Louis Science Center with my wife and her friend to see the Star Trek exhibit. After being there about 45 minutes I was approached by a security guard who asked me if it was a real knife. I responded affirmatively and he asked me to come with him.
The best part was the 4 other guards that collapsed on our position. This must have been the biggest deal ever for them. I asked if I could leave the knife at a desk and pick it up when I left and was told I could not. So I walked to my car, escorted by one of the guards, tossed the knife in and walked back to the exhibit.
Now, I live in St Louis. St Louis city has a shooting every day and a murder every third day. In a community of only 320,000 that makes for a pretty serious violent crime rate. For the security guards to get all worked up by a dude peacefully walking about with a knife shorter than 4" is silly. I'm sure it did violate one of their rules but it's a silly rule to have, one that has no affect on crime on premises I'm sure.
Oh well. All hail the nanny state.
