Koenig Arius Gen 4 Smooth Titanium Handle M390 Blade Blue Backspacer

SKU: B3833J

A Very Sought After knife, Sold Out Worldwide. One Of The Smoothest & Most Precise Knives Money Can Buy


Bill koenig was shot to fame in the knife community when he made his most popular design, the Arius. It was a revolutionary knife, not only for its unique handle and blade design, but also because of the extremely tight tolerances and exceptional precision & build quality. This made for one of the smoothest knives ever produced in any price range. The word got out in the knife community quickly and the supplies dried up even quicker. The Koenig Arius has remained one one of the most sought after knives through its 4 different generations and also one of the hardest knives to acquire.


The Arius Gen 4 features a smooth titanium handle, contoured and bevelled, with a machine titanium pocket clip. The blue anodized titanium backspacer features an integrated lanyard hole. The blade is made of Bohler M390 steel. It features a 3D milled blade fuller and is two-tone finished. 


The Arius has arguably one of the smoothest deployment actions we have seen in any knife, regardless of the price. The handle ergonomics are exceptional, making the Arius a knife you will enjoy handling and flipping.
