The pressure blade plate is thickened and cast in fine steel, and the contact area with the blade is increased, making it less likely to break during use;

The thickened blade is made of vanadium steel and will not curl or chip after long-term use;

The second and third gears are all weighted so that they are less likely to break the teeth when cutting large steel bars;

Thickened side cover, 8-hole design, no breaking or deformation;

The gear shaft is precision cast, and the gear meshing part has undergone high-frequency or quenching and tempering treatment, making it stronger and more wear-resistant.
