The RD-6 (part of Ontario's Ranger series) was built for combat deployment in the most unforgiving terrain on the planet. It is a fantastic 6.6" general purpose large survival and utility blade. It has a 5.65" cutting edge. Like the other RD models, it features .25" thick 5160 Carbon Steel.
The pommel is a stout defensive tool that features aggressive jimping and a generous lanyard opening.
