This Medium Jack is a part of the Working Knives collection from Case Knives. The Working line salutes hard driving team players who answer the call and give it their all until the work is finally done. The Medium Jack pocket knife is a pattern where the blade or blades open from one end of the knife. This knife features two blades, the clip and pen blades. The clip blade is commonly used as a multi-purpose blade and preferred for detail work. The pen blade is great for small detailed uses, especially for everyday use such as opening envelopes and boxes. This knife is constructed with Case Tru-Sharp stainless steel which is a special high-carbon steel that helps the blades hold an edge longer than conventional steel. It also offers extraordinary blade strength and corrosion resistance Everyday carry pocket knifeClassic black jigged bone handles with script style Case inlay shieldPen and clip blade
