Three level lever composite transmission: unique crank connecting rod mechanism design, outputting maximum shear force with minimal hand force, easily cutting the toughest metal sheet.

Multi angle blade configuration: usually provides three blade types: straight head (center cutting), left bend (counterclockwise curve cutting), and right bend (clockwise curve cutting), to adapt to different cutting path requirements.

High carbon chromium vanadium alloy steel blade: made of aviation tool steel and subjected to special heat treatment process, it maintains ultra-high hardness of the blade while having excellent toughness.

Micro gap precision adjustment: The blade gap can be finely adjusted to ensure the cleanest cut when cutting materials of different thicknesses, without burrs or deformation.

Double sided grindable blade design: Both sides of the blade can be ground and repaired, extending its service life by several times.

Ergonomic Handle: Large circular handle design that allows four fingers to be fully inserted, providing maximum leverage and handling stability.

Anti slip and shock-absorbing grip: The surface is designed with anti slip texture, and there is a shock-absorbing structure inside, which ensures long-term use without fatigue or slipping.

Visual thickness gauge: Some models are equipped with a thickness indicator at the handle to quickly determine the maximum material thickness that can be cut.

Aerospace maintenance: on-site trimming of aluminum alloy components such as aircraft skins, fairings, and cabin doors for precise shape correction.

Automotive sheet metal repair: Cutting body steel plates and making patch plates are iconic tools for automotive sheet metal processing.

HVAC installation: cutting galvanized sheets of ventilation ducts, making irregular joints and flanges.

Architectural decoration engineering: cutting decorative materials such as aluminum-plastic panels, stainless steel decorative strips, and skirting boards.
