CONSTRUCTION & MATERIALS
The Kilimanjaro Gear Firma is comprised of G10 Handle Scales, a stainless frame and spacers, and 8Cr13MoV blade steel. Besides all of the other tests I threw at it, the Firma was buried in the mud and snow for over a week and only had a few spots of surface rust on the blade (which rubbed right off). 

EASE OF USE
The Firma is a tip-down carry knife that lives in a world of tip-up carry knives. Because of this, It took a few days to get used to deploying it properly. Although it’s a little heavy, the Firma’s ergonomic shape makes it one of the most comfortable knives I have ever used on a day to day basis.

STEEL QUALITY/EDGE RETENTION
The Firma utilizes 8Cr13MoV blade steel which has an HRC of 58-60. It sharpens up quick and easy and maintains an edge for a considerable amount of time. Additionally, its way more corrosion resistant than I had expected.

DURABILITY
The Firma comes with a lifetime warranty, but I am not sure you’ll ever use it as it’s one tough cookie. The surface rust is not a concern or deterrent and the handle scales look a little worn, but in regards to what I’ve put this knife through, it’s held up exceptionally well.
