The funny thing about weapons is how easy they are to buy off the street here at the other market. It quite literally is a street market in which people just lay out whatever they want on the ground over a little bit of fabric. It doesn't just relate to little daggers but actual swords. Guns however, I don't think I've seen those available. Rather little things from the Cold War like gas masks and such.
I do want to return to that one before I leave Georgia, it has some genuinely fascinating pieces of history up for grabs. There are even war trophies that people picked up from World War 2: Nazi hats, pins with the swastika, etc. Also various items from the USSR. Never seen anything like that so casually on sale. As Indiana Jones would say: those things belong in a museum! ;^)
I totally agree, those things are museum stuff! But yes, if you have the chance to go again and buy something it would be great!
