I have quite a few Ritter knives, from the early days of the RSK Mk1 (purchased with the molded sheath), to the very sexy RSK Mk4 Gentleman's Folder, and most recently a beautiful orange RSK Mk1-G2, and I don't recall getting a free Tuf-Cloth.

BTW, I'm so tempted to buy the new RSK Mk3-G2 fixed blade knife. I have the first generation Mk3. It's been my favorite fixed blade knife since I got it. Highly highly recommended!!
