Here is a Mod. 18 I have never shown. It was made with a Soligen Humpback Blade and is marked with a Separate S and Stainless along the Ricasso. I really like blades like this. It has a JRB Riveted Sheath that has been modified. Another item that I like.....Modified Sheaths. The keeper strap was moved from the left side to the right. It came with a white stone and the entire rig is in outstanding condition.
