It's gotten to the point where I can pretty much exactly predict people's reactions to my sword. Upon first seeing it they blink, sometimes take a step back (even if they don't, they usually retreat minutely) and then begin to stare.
When I offer it to them and they take it in their hands, everyone says, "Oh." Most people seem to instinctively hold it pretty well and you can see their eyes travel up the blade and then out in front of themselves, suddenly picturing somebody there who's about to get cut in half.
Nearly everyone says something like, "It feels like a weapon."
The guy with the Blue Orchid said exactly that. And yeah, it felt different than his sword. Maybe just cause we're katana geeks and get ourselves all wound up, I dunno. But people seem to have the same set of reactions to it.
Except for Japanese people. Non-swordy Japanese people run away (seriously -- I showed it to some of my co-workers in Tokyo and they scrambled back from it so fast one girl fell over a table), and swordy people just go, "Mm. Very good."
