Tapping Tools

RRIMCISSION

Harvesting natural rubber demands making a perfect incision: cut deep enough to release the, yet shallow enough to avoid the tree’s delicate inner growth layer, the cambium, which is essential for its long life and bark regrowth. Early curved knives, such as the Pisau Jebong and regional Pisau Toreh types, established the ideal shape for a good cut, though success depended entirely on the tapper’s mastery of the cut. Research quickly introduced control: tools under Alat Toreh and the RRIMBARKIS featured gauges to measure bark use, while the modified Jebong Ubahsuai (1984) added physical stops to lock the blade depth, guaranteeing the tree was never harmed. Even older mechanized tools like the Pisau Elextrolux (1982) offered guaranteed, consistent cuts, protecting the tree and making the job easier. Specialized knives, including the Pisau Torehan Menaik Terkawal, allowed tapping high panels on older trees, extending their productive life.

The latest innovation is the RRIMCISSION (2019), a breakthrough featuring replaceable blades. This system guarantees a perpetually razor-sharp edge, with a single blade capable of tapping up to 6,000 trees without manual sharpening. This high-volume precision maximizes latex flow, reduces physical effort, and minimizes tissue damage.
