Balisongs And Caviar A Balisong Collector Special Exhibit ST3-X This is another large balisong. It's about 11 1/2" long overall (about 29.8cm) when open. The blade is made from Jim Ferguson's Turkish Delight Damascus steel. Mr. Ferguson specializes in Nickel Damascus which is made by combining a high-carbon steel, C1095, with a high-nickel alloy, N200. High- carbon steel etches to dark gray to black. Nickel does not etch but remains bright silver. The result is great contrast. This blade, by the way, has about 250 alternating layers of C1095 steel and nickel in it. The edge of the blade features Pabu's exclusive 3D edge. This type of edge is not ground; it is hand-filed. There is no other shop that does this sort of 3D blade work. The blade profile is a sort of clip-point utility with a zero-bevel false edge on the clip.
