Jenlis Weed Razer – Aquatic Weed & Grass Cutter
This cutter focuses on reach and efficiency with a V-shaped head that creates a razor-sharp, 48-inch cutting path. Weighing only about 8 pounds, the Weed Razer is easy to cast and sink, enabling base-level cuts at the weed’s bottom. It includes a 25-foot rope along with deflectors and a blade sharpener.

The Weed Razer Express is designed for compact ponds and tight spaces. It employs razor-sharp V-shaped blades that clear a 30-inch-wide path. The device weighs about six pounds, yet sinks efficiently to cut at the base of pond weeds. It comes with a 5-foot handle and is optimized for shoreline accessibility, keeping docks and shorelines clear for swimming, boating, and fishing. Choose this if you need a portable, easy-to-deploy solution for small water features.

This dual-blade system supplements the single-blade design with increased cutting power, suitable for larger ponds or river sections with dense vegetation. It uses a 48V drive system and a 650W brushless motor to deliver stable performance for aquatic weeds, reeds, lotus leaves, and pond vegetation. The mounting and operation mirror the single-blade model, with the same user-assembled battery requirement and quick-start control. Best for: larger water bodies needing faster clearance; better for heavy growth than single-blade variants.
