Originally used for weeding, this sickle is also sold as a repotting sickle because it's frequently used when repotting bonsai.
A repotting sickle is a specialized sickle used when repotting potted plants or bonsai. It's inserted between the pot and the compacted soil (root ball) to create a gap, making it easier to remove the plant from the pot. It allows for smooth cutting along the inner wall of the pot without damaging the roots.
This sickle is commonly used for miniature bonsai.
