This combo kit of a Roll Cutter, 3 Figure hand Cultivator, Big hand Trowel, and a 1 inch Khurpi are essential hand tools for small-scale gardening, each serving a distinct purpose in cultivating and maintaining your garden. 

The hand cultivator is a small tool with tines or prongs designed to loosen and aerate soil.  It's ideal for breaking up clumps of dirt, mixing in amendments like compost, and preparing the soil for planting.  It's particularly useful in smaller gardens or raised beds where larger tillers can't easily maneuver.

The hand trowel is a small, flat, scoop-shaped tool used for digging, planting, and transplanting. It's perfect for creating small holes for seeds or seedlings, moving soil, and carefully lifting plants. 

The khurpi is a small, versatile hand tool with a flat, curved blade. It's used for various gardening tasks, including weeding, digging, and scraping.  It's particularly useful for removing weeds close to desired plants and for light soil cultivation. 

The roll-cut mechanism of the cutter and sharp blades make pruning tasks smoother and less tiring. 

These three tools together form a basic but highly effective set for small-scale gardening. The hand cultivator prepares the soil, the hand trowel helps with planting and transplanting, and the khurpi assists with weeding and other fine-tuning tasks.
