I purchased this last year and it has been in the safe ever since as I have a regular Praetorian that does all of the grunt work. Medford Praetorian Ti with an S35 Vn Vulcan Tanto Blade. The frame is flame treated titanium. This is a very impressive knife and you can see the difference in thickness next to the standard Praetorian in the last pic. Original price was $1,800. I am offering it up for $1,450 shipped.
