Boker Swell End Jack – Birch Folding Knife

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 centre 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 green stabilised handle scales are made of local burl birch wood, which is characterised by its rich colour and striking grain. The characteristic bolsters are made of nickel silver. Handmade in the Boker Knife Manufactory in Solingen. With high-quality felt case for storage.

The history of Boker can be traced back to the 17^th century. In the 1800’s the German tool maker was producing swords and other blades for use in the various wars that were going on in Europe at the time. In the1860’s the company had split with part of the family emigrating and setting up factories in America. The German and American factories produced similar products.  Both used the “Tree Brand” logo. The “Tree Brand” logo represents the giant chestnut tree that was at the front of the original Boker factory in Remscheid, Germany in the 17^th century.
