I think my friends have mostly come to terms with my knives. They used to say "wow, that's a scary knife", since I had been moving up in size and nastiness, from a Gerber AR 3.00 to a CRKT M16 to a Buck-Strider folder to a BM AFCK. Now they just say "The God of Knives!" whenever I pull it out to either use myself or to lend to one of them.
However, I've had someone ask behind my back why the university hasn't kicked me out yet... Hrm. At the time I was the only knife-using person opening up food packages for 30 people. Someone else there asked me why I had the knife, right as I was cutting their food open.
I haven't used my Strider MFS in public yet. That's just a little over the top, with the tiger stripes and paracord. I do carry it though, since you never know when you might have to hack open the wreckage of a car to save people. Ah the daydreams of a knifenut.
(Anyone remember Chris Connoly/Perilous Truth's experience?)
