I have gone through HK customs with 12 Khukuris in checked luggage
and one time I had 6 Thai Swords
Each time I was stopped and my bags checked, they took the knives out, saw and felt it was a live blade and asked me what it was for, my reply was "GIFTS", supervisor was called over and she looked at it and said I could go through, one customs guy even said these are great for killing people, I just gave him a shocked look and again said "GIFTS"![]()
