In the latest issue of this Russian Knife Magazine (Klinok), July 2008, Dmitry Samoylov wrote an article about knife lanyards(pgs. 47-51). Dmitry had sent me some questions last year, and I provided answers and some photos that he used for part of the article.
The copy of the magazine he sent me arrived today. Although I don't read Cyrillic, it's a very nice magazine with great photos of knives, swords, and other edged weapons and tools.
