INCREDIBLE ITEM! This is one of the knives that was especially made by the effects crew for several important scenes. The knife (-a-) can be seen being handled and thrown by the evil assassin twins played by the Meyer brothers. The knives were custom made under the direction of John Brown. Several models were created including one that was cut-down (-b-), the knives that pinned Roger Moore aka James Bond to the barn door. The twins troughout the film used this particular knife and sheath and it is one of only three (!) believed to have survived to date. THIS IS AN INCREDIBLE RARE MAJOR PROP OF BOND HISTORY WITH CRYSTAL CLEAR HISTORY!
