This Terrain 365 Invictus-ATB knife is a unique knife that is constructed without any steel, making it completely rust-proof. Prometheus Design Were partnered with Terrain to create this knife.  Feels solid in the hand, flips with the thumb stud smoothly on its ceramic bearings. Strong detente.  Drop closes. Definitely a large knife. Comes with zippered case in original box, and includes small vial of lubricant.

I am not the first owner of the knife; I bought it about a year ago but only carried this a couple of times and cut only cardboard once with it.  It appears to have been sharpened at least once before I purchased it.  In excellent condition except for a few scratches on the backside of the blade (seen in the photos) that might have occurred when it was sharpened.
