9/11 did the utility knife a lot of damage as a tool.
Ha! Funny you mention that.
In college I played violin in the university symphony. The dorms weren't air conditioned and I lived on the first floor, right above the boiler room, so the humidity was horrific.
Humidity isn't good for voilins, especially 100+ year old violins like mine. One day shortly after 9/11/01 I was sitting in my room working one something and heard a pop. I didn't think a whole lot about it until I got my fiddle out to practice later that evening and the bridge was snapped in half. The humidity caused the top plate to expand and the upward pressure on the strings was more than the bridge could take.
Fortunately, I had a few semi-finished bridge blanks in my case. At the time I was EDC'ing a Kershaw and no other knife I had with me in the dorm was thin enough to do the delicate work to cut the bridge.
So off I went to Wal Mart in search of a thin knife.
Box cutter! Brilliant. Picked one out, the same one we're talking about in this thread actually, and went to pay. At the time, and my driver's license is proof of this, I guess I kinda looked like a terrorist with my full beard and the cashier wouldn't ring me up until the manager approved it

.
But what I learned was, the box cutter is the absolute best knife I've ever found for cutting violin bridges. Vastly better than knives actually made to cut bridges because the handle is smaller and much easier to control.
Box cutters are great tools, but this Stanley is heavy. Far too heavy to EDC. If you need to EDC a box cutter, either put it in a holster on your belt or get a plastic one. To this day, that box cutter lives in my violin case and I've used it several times to cut bridges on the fly before concerts for people. As naked as I feel without my EDC, I'd feel equally naked without that box cutter in my violin case. If I ever had to fly, security would just have to deal with it.
