The S.E.K. model is one of the most successful Original Eickhorn designs of the last years. Leading German Special Forces units picked this knife to add it to their special purpose equipment. The re-designed blade of the S.E.K. has now a spear point pattern. The full size back of the blade adds a lot of strength to the knife, which makes it even more useable as an entry tool. A Kydex Sheath and multilock-adapter are included.
