having been to Afghanistan, and saw many, many hodgie shops and bazaars,(not all of them on base, or fobs either) there is nothing i would buy there that i would think was in any way real or not faked. as for not used to death, i've seen 5 lb sledge hammers that were worn through to the handle, claw hammers with the claws worn away, saw an anvil once that was so used you could almost eat cereal out of the dent in the top. if something can be used to death Afghans will do it.
as for bazaars/hodgie shops, we stopped at one that was the size of a yard shed,(6x8) it would have taken an hour to see all the crap in this hut. european Marlboro's, red bull, DVDs, cell phones, ipads, iphones, dvd players, mp3 players, benchmade switch blades, eotechs, aimpoints, Leupold hollow sights, magpul slings, 511 uniforms, north face clothes, and even Lego's. i bought a dvd of the new "true grit" movie 2 months before it hit theatres, i wouldn't put anything past an afghan. only saw 1 enfield tho(in use), seems odd since its the 2nd most popular gun there, who knew.
still have a few extrem ratio knives from over there.
a kukri would be childs play.
you can get tourist visas now too.
my opinion, if it came from Afghanistan, its a fake, but it is a knife from Afghanistan, so not a total fake. you got something that most on here don't, a real war relic, no matter if it was made last year or last century. enjoy it.
