High-quality materials: The blades of the gardening scissors are made of high-carbon SK5 steel, which resists rust and maintains sharpness. Special process: the blade is heat-treated to achieve a hardness of HRC62 or higher, enabling it to cut branches up to 30mm in diameter. Hard chrome plating on the blade surface provides excellent protection against rust and sap corrosion, reduces friction, enhances smoothness, and extends tool life. Plant health: Sharp blades ensure precise, clean, and sterile cuts without damaging plants, promoting healthy growth. Ideal for pruning and harvesting in gardens, orchards, nurseries, potted plants, greenhouses, hydroponic systems, fruits, herbs, flowers, bonsai, and more. Safety: Garden shears feature a safety lock to prevent accidental injuries and protect the blades when not in use. Comfortable and effortless: The pruner handle is constructed from aircraft-grade aluminum alloy, lightweight and durable. The ergonomic, non-slip design reduces hand and wrist strain, offering comfort and vibration reduction during extended use.
