The double shoulder sheath puts a blade under each arm for maximum access. As the saying goes, "one is none and two is one." For a hawk and knife it's a perfect solution, or double blades for ambidextrous use. Another option is a less lethal force tool like a baton along side a blade or pair of cuffs. The options are endless. Contact us for your blade, type of draw, color, or other special options. Current factory blades can also be ordered and combined into this sheath system.
