Multiple bars twisted damascus also called Turkish pattern is generated by multiple location damask square rods be twisted and then connected to each other by forge welding. I use bars with 10 to 12 mm cross section. The more bars are connected the more difficult it becomes because they can easily tilt the back when forge welding. When that happens the whole preparatory work was in vain. A false hammer blow can destroy so the entire preparatory work. The material loss is particularly high in this type of pattern, it is around 80%. After welding the bars, the package is not from forged, but grinded off on both sides up to the thickness of the blade. These are 2.8 mm for a kitchen knife. This is necessary because the pattern of this damascus steel changes depending on the grinding stage. All the beauty of this steel is evident only when it penetrates through the loops in the Interior.
