This representative of the legendary Seal series from SOG not only compels with its elaborately designed and extremely slip-proof handle with steel insert whose end has an integrated impact element. The blade with aggressive serrations is titanium-nitride-coated and extremely corrosion-resistant. The multi-functional plastic sheath therefore also supports underwater uses. The sheath was given special attention, which is why it is not only used to store the knife. A removable belt adapter secures the sheath to the belt either directly or with a steel clip. When the belt adapter is removed, particularly large openings are used for easy installation, e.g. of a Tek Lok. A steel slider covers a pocket that allows safe use of the knife as a belt cutter when in the sheath. A sharpener and a fire starter are also securely integrated as captive elements in the sheath. A real multi-talent that dramatically improves the functionality of the sheath or the sheath-knife unit, without burdening the carrier with additional weight or packing volume.
