Its 50 cm (20″) laser-cut, double-sided, and diamond-ground blades deliver a surgically clean cutting pattern, powered by the high acceleration of its efficient EC engine.

An ergonomic control handle featuring a self-resetting Ergo lever ensures comfortable operation for both left- and right-handed users. For added convenience and safety during transport between jobs, the head can be folded flat, reducing the total length to just 132 cm. The tool is also supplied with a blade scabbard and features an integrated tip protector to prevent blade damage when working near walls or the ground.
