This took place between an Afghan truck driver and myself during my first deployment.
This place isn't near Russia but since we would see old Soviet tanks it could count as the surrounding area.
My squad and I were searching vehicles and one of the Afghan drivers noticed my prized bowie knife hand crafted from Germany which was purchased just for my deployments and asked to look at it.
Being a friendly guy, I handed it over as he admired my tool.
Pretty soon, and unbeknownst to me beforehand, this turned into some kind of barter which must have been the custom.
Since none of spoke the same language he would try to indicate that he wanted to leave with the knife which I obviously would not allow, as it was my special knife.
After ten minutes of arguing, he finally gave me back my knife reluctantly and we gave the proper good by.
I never saw him again shaking this encounter off as a "newbie" move on my part for being so dumb and oblivious. Yet I continue to own my prized knife (which was almost lost several times) with the dust from Afghanistan still on it.
