About the Traditional Kama Heritage

The sickle (kama) has deep agricultural roots in traditional Japanese farming, where curved blades were essential everyday implements for harvesting rice, cutting field grass, and clearing dense underbrush. The inward-facing curve provides controlled cutting leverage on fibrous growth, making it a distinctive piece of traditional agrarian design. KATSU has re-engineered this heritage tool into a refined folding format for modern tool collections and outdoor woodcraft tasks.
