This technique is more complicated and time consuming. Using a square tube, 2x2 inches high and 4 inches long. I fill the tube with steel rods of varying dimensions and nickel sheet, this way I create an image that will be visible when the steel is finished. This procedure takes a very long time. I forge weld the “package” together. When it has cooled down, I cut slices that I then forge weld together again, carefully shaping the steel to fit the desired blade or bolster.
