Damascus Steel Fold-Up Knife Retired. Here is a fold-up knife made of imported Damascus steel. These were made in very limited batches. Each of these hand-crafted knives comes with a custom wooden box as seen in the images. The boxes are approx 6 7/8" x 2 3/4" x 1 1/2" and weigh (with the knife enclosed) under one pound at 0.82lb. When in its folded state, the knife is approximately 4 3/4" long. When the knife is out, it is approx 8" long. The knife is in good, unused condition with one very small black mark on the handle. These were all a limited run of custom knives, all made to the company's design, and are no longer being released.
