About KATSU FS01

In ancient Asia, common people were forbidden from owning tactical weapons like swords and knives, facing severe consequences if caught. They had to use farming tools to resist oppression.This is where the origin of Kama as a weapon lies.

The experience of cutting grass in the fields inspired early users of the Kama and led to the development of tactical movements suited for its use. Instead of chopping or stabbing at the enemy's frontal body, the unique inward-facing edge of the Kama allowed for hooking and pulling actions to target vulnerable areas such as the arms, legs, and neck, dealing fatal blows to the enemy.

This is what sets the Kama apart from swords or knives. Moreover, the Kama is lighter in weight and more agile, making it easier to wield, and thus, it has always been recognized for its effectiveness in close combat.

In collaboration once again with Mr. Nemoto Tomoyuki of NEMOTO KNIVES, KATSU KNIVES proudly presents this exceptional folding sickle, a one-of-a-kind weapon in the world. Through the use of high-quality materials, impeccable craftsmanship, and modern intricate design, we breathe new life into this time-honored traditional weapon, ensuring its relevance in the modern era.

  • Fast and Versatile Deployment

Just like the renowned KATSU FA series, the FS01 supports both folding and quick one-handed opening, allowing for swift and effortless deployment during critical moments. Its design ensures smooth and seamless handling, giving you the edge in real-world scenarios.

  • Lightweight Handle

The FS01 boasts a titanium alloy main body frame with carbon fiber protector,, resulting in an incredibly lightweight design. This combination provides exceptional strength and durability without compromising on weight, making it perfect for those seeking a reliable and agile tool.

  • Enhanced Tactical Capabilities

The FS01 is equipped with a Shark-tail shaped tool at the tail end, providing an additional tactical option in emergency situations. Furthermore, the inclusion of a lanyard hole offers versatile carrying options, allowing you to keep it within reach at all times.

  • Axis Lock

The Axis system works using a small, hardened spring loaded bar that moves back and forth in a slot made into both steel liners.

Due to its integrated build, the Axis allows for ambidextrous operation easily and quickly. In addition, its overall construction allows for even greater engagement with the tang as the knife is in use.

Overall, the Axis mechanism allows for quick and secure deployment of the blade, improving the strength of a typical folding knife with this construction.

Our knives are built to last. Cleaning and caring for your knife will maintain performance and enhance the life of your knife.

Tips for Caring Folding Knives
  • Keep your knife dry; that means the entire knife, not just the blade.
  • Keep your knife clean, particularly moving parts and locking devices.
  • Keep your knife oiled; especially pivot points and the blade. Oil at least twice a year.
  • Keep your knife sharp; a sharp blade is safer than a dull one.
  • Again, store your knife in a dry place.
Tips for Caring Kitchen Knives
  • Always use an appropriate cutting board in the kitchen to get the most out of the sharpness of your knives.
  • Cleaning knives after each use will keep them in the best condition and promote food safety.
  • Knives require a safe dry storage place, and a knife block is perfect for storing knives.

This blade is as sharp as it is unique. Very lite weight and extremely detailed build quality. The most innovative knife design I have seen in awhile and lucky to add to my collection.
