The Mad Dog DSU 2 was originally commissioned by Lt. Commander Daniel Kerns (RIP) of the US Navy Deep Submergence Unit. The Navy DSU was in need of a knife that would be able to cut various sizes of extremely abrasive ropes like Spectra and Kevlar in quick fashion along with being able to handle extreme depths (12,000′ +) without blowing apart. Mad Dog quickly answered this problem with a fully serrated variant of the hugely successful Mad Dog SEAL ATAK. The DSU and DSU 2 were designed and developed in early 1993 and approximately 200 of these older DSU 2 knives were made over the next couple of years. Most of the original DSU 2 knives were sold to the Navy DSU, commercial and sport divers along with other various specialized people. A DSU 2 knife was actually credited by Lt. Commander Daniel Kerns with saving a Naval support ship from sinking. Armed with his Mad Dog DSU 2, Lt. Commander Kerns cut loose an out of control piece of heavy equipment in class 5 seas held by a piece of 2″ Spectra in a single swipe. The DSU 2 is extremely effective for what it was designed for.
This Mad Dog DSU 2 is in excellent condition and has only been taken out of the sheath to be admired once in a while so it shows a little bit of sheath wear. The knife has the original edge and 3 sheaths, ATAK, Cross Draw & Dundee. The Cross Draw sheath is extremely rare, you hardly ever see them, but they are super.
