Welcome to the official Common Sense Self-Defense / Street Combat site. Founded by Grandmaster Bram Frank, CSSD-SC has been the hub from which he has promoted his Combat Arnis and Modular systems, along with his knife designs.

What are your CSSD goals today?

Limited Knives and Tools Now Available

Bram Frank is clearing out his knife collection. He has prototypes, custom one-offs, limited run knives, etc. All that are taking up space. He wants them to go to a good home, to someone who will enjoy owning them or even using them.

This is your chance to get something that no one else has. Go look at what is available, but remember, once a tool is gone, it’s gone. They are all single item purchases.

The New Knives Are HERE!

After months of chaos, which includes, but is not limited to… production delays, shipping delays, government interference, and we can’t forget to mention the instigator in most of that… COVID, we happily introduce to you… the Sister Christian, the Kopesh, and the Desangut which comes in 3 different blade styles and a Trainer Drone.

These knives are now In Stock and ready to ship. Order yours today!
