I have for sale a Hackman balisong, also known as the "CIA advisor knife" rumored to have been issued during the Vietnam War.  Still debate on whether it is true, but folks are paying for them as though it is.  As can be seen in the photos, this one has some small marks on 1 side of the blade I could not remove. Due to the marks, my asking price is quite a bit less than what these have been selling for. 


Buy with confidence. I have bought and sold guns and knives on several webistes including Armslist, Texas Gun Trader, and Knife-Market.com.  I am a retired local peace officer in the  Houston area. My former employer can be verified and I can provide other references as well if needed. msg me for additional info threefour6364zerozero81.  I have several other knives for sale I will be listing soon. Don't miss this unique knife. Thanks for checking out the ad.
