This is a fantastic bushcraft tool from Boker plus. The Optima is a folding knife with an interchangeable Saw blade which comes with a quality leather pouch. The knife blade is 9cm in length, made from Aus 8 stainless steel and is one hand opening. (it does have a half stop though which i personally find annoying). The saw blade is 440c stainless steel. The handle is textured G10, is grippy and feels like micarta. The whole package is in good condition.
