The 6/8cm Spare Spring Pruning Shears are designed for all your gardening needs. Made from durable spring steel, the outer diameter of the spring measures 60mm, with an inner diameter of 50mm and a free height of 80mm. The spring is chrome plated for added durability and resistance to corrosion. These shears are perfect for pruning branches, picking fruits, and trimming bonsai trees. The cocoon spring is wound tightly, making it strong and long-lasting. It is suitable for any tool that uses a spiral spring. Installing the spring is easy - simply measure the correct size by looking for two lugs/knobs on each handle of the pruning shears. The spring should be slightly compressed when installed in the open position to ensure a secure fit. The volute spring used in these shears is a conical compression spring, designed to prevent the coils from squeezing each other under compression. In addition to gardening, these shears are also suitable for kitchen use. They are lightweight and make cutting food a breeze. After installing the spring, the shears become lightweight and labor-saving. The package includes 1 spring accessory, so you can easily replace the spring when needed.
