The Case Exotic Handle series started in 2001 and is still going strong. The tang stamps all have EX or IV handle codes on the model number. Examples: EX201, or IV254. The handles are all semi-precious materials used in various combinations. These knives are beautiful and at the higher end price wise. And they have tended to appreciate nicely. The result is a very nice collectors niche. Clicking the lower right corner link on a knife will take you to the price and other details of that knife. The black and white pictures are place holders. If you have color pictures of any of the black and whites, send them to email@example.com and get your name added to the site as a Case authority.
