The Boker Swell-End Jack is another classic knife shape, which was to be found on European farmers’ markets and in the typical general shops of American settlements since the turn of the century. The handy pocket knife owes its name to its traditional design, which becomes noticeably wider towards the end of the handle, thus shifting the knife’s center of gravity backwards. In addition to the satin-finished main blade of ice-hardened N690 with 60 to 61 HRC, the knife is also equipped with a cap lifter that can also be used as a screwdriver. The blade has a modern ricasso and is opened by nail nick. The operating safety of the slipjoint is increased by a 90-degree arrestor during opening and closing. The handle scales are made of deceptively realistic-looking synthetic horn, which combines the low maintenance and robustness of a synthetic material with the look of a natural material. The characteristic bolsters are made of nickel silver. This knife is handmade in the Boker Knife Manufactory in Solingen.
