Don't send knives to Russia. Period.
I had pretty good luck for awhile but my last experience has made me stop shipping over there altogether.
I shipped a sprint Spyderco PM2 via USPS Express Mail with insurance to a guy over there that I had shipped to before. Everything was legit on the customs form, etc. Long story short, the knife disappeared and I got a letter from USPS saying that my package was damaged or received with missing contents. But then USPS denied my insurance claim by saying that I had shipped a prohibited item and then they quoted this:
USPS has denied my appeals stating the same law. I even called and talked to them and they say that a pocket knife, a folder, falls under that list of prohibited items because it is similar to the items listed.
Sorry, my Russian brothers, but I am done shipping over there. It's just not worth the risk. I hope my story helps someone else.
