Firmus in Latin means Strong, Steadfast, Reliable, and Powerful. We’ve designed and hand-crafted the Firmus to be a professional and quality knife suitable for many uses and live up to it’s namesake Strong, Steadfast, Reliable, and Powerful.

All of our folding knives parts are polished and finished to a tight tolerance with the best materials available.

The Firmus can be changed from a right-pocket oriented knife to a left-pocket very easily with the movable clip.

This lightweight multi-purpose knife is great for EDC carry, camping, tactical, and any use. It comes with our lifetime CY6 Warranty.

For bulk orders, our 1790 R.D.Q. blade deployment system can be added for added value and performance.

The handle is made of G10 material with a steel liner with locking mechanism.

We’ve included bearings on the pivot pin to enhance the user experience. This flipping action is very solid, sounds great, and to be candid, can be addictive to opening. Be careful, the D2 steel blade is very sharp.

Part of our CY6 Lifetime Warranty includes sharpening. If you ever need your Firmus to be cleaned and sharpened, please contact us and we will give you an RMA number for sharpening. We will send it back at our expense.

We hope you love your new Firmus as much as we have loved hand-crafting it for you in South Carolina!
